Hydrochloric Acid Test Lab Report

Ever wonder about the chemical makeup of tablets that people take for pain relief? Before a tablet can be successfully made, the limiting and excess reactants must be considered. The limiting reactant will affect the amount of the product that can be made. Another reason why the starting reactants must be determined carefully is to make reduce the amount of the reactant in excess so that reactants are not wasted. This experiment uses an Alka-Seltzer tablet. Alka-Seltzer dissolves in water and is an antacid and a pain reliever1. The Alka-Seltzer tablet has many uses such as relief of headaches, ingestion, heart burns, or even upset stomachs2. The active ingredients in an Alka-Seltzer tablet is aspirin, also known as acetyl-salicylic acid (C8H12O4), citric acid (C6H8O7), and sodium bicarbonate (NaHCO3)2. The aspirin in the Alka-Seltzer tablet helps with pain relief. Because of the acid-base chemistry (Brønsted-Lowry), citric acid and sodium bicarbonate produce O2, which makes the tablet fizz when it is dropped in liquid. The Brønsted-Lowry theory shows how the Brønsted-Lowry acid donates a hydrogen ion while the Brønsted-Lowry base accepts the hydrogen ions3. The remaining NaHCO3 that is in excess post reaction with the citric acid is what is used to neutralize stomach acid which helps relief heart burn2. The problem in

The makeup of a compound drastically changes its intermolecular forces (IMFs) with the polar silica gel of a TLC plate; this concept is responsible for the variability of Rf values observed throughout the course of lab. The weaker the IMFs, the further a compound will travel through the silica. For instance, ionic interactions are the strongest IMF, but were not present during this experiment. H-bonding IMFs had the greatest impact for our specific compounds. Resorcinol and 3-chlorobenzoic acid exhibited low Rf values, due to its ability to H-Bond to silica’s hydrogen donors and oxygens acceptors (See graph 1). Both were adept to strongly H-bonded to silica because the compounds contained at least 1 H-donor and 2 H-acceptors. Thus, stronger/more

Antacids are medicines that can be bought over-the-counter which are taken by mouth and can help to quickly relieve acidic refluxes in the body.https://en.wikipedia.org/wiki/Antacid The major symptom of gastroesophageal reflux disease (GERD), are taste of acid, bad breath, chest pains, etc. GERD is a long term condition where stomach contents come back up into the esophagus. Complications include esophageal strictures and Barrett’s esophagus.https://en.wikipedia.org/wiki/Gastroesophageal_reflux_disease An Esophageal Stricture is a narrowing or tightening of the esophagus that causes swallowing difficulties.

First, a 100 mL graduated cylinder was obtained and filled with 35 mL of water. A pipet was used to attain a more accurate amount of liquid. The water was then poured into a beaker, which was weighed on an analytical balance. Next, an Alka-Seltzer tablet was obtained and the weight measured using the same balance the weight of the beaker was measured on. When both masses were recorded, the tablet was dropped into the water. The liquid was swirled to allow for the tablet to dissolve completely. After the fizzing had stopped, the beaker was once again weighed and the mass was recorded. Each step was repeated seven more times for a total of eight trials. However, with each trial the liquids added to the beaker changed. In each new trial, an additional 5 mL of vinegar was added and 5 mL of water was taken away. Thus, beaker one had 0 mL of vinegar and 35 mL of water; beaker 2 had 5 mL of vinegar and 30 mL of water; beaker 3 had 10 mL of vinegar and 25 mL

Antacids is a group of medicines which help to neutralise the acid content of your stomach (Patient Online). Many antiacid makers claim that there products are always the best to be used. Antacids can be used to treat: heartburn, indigestion and symptoms of acid reflux. Alka-seltzer is known for being a great painkiller that provides effective and fast relief of headaches and upset stomachs. There are many other brands that are similar to Alka-seltzer such as Tums & Rolaids. Tums are known to be America’s #1 Antacid brand, that goes to work instantly for fast heartburn relief (TUMs.com). Rolaids share some similarities from both Alka-seltzer and tums, with a slight difference in ingredients. During this experiment, the main focus is figuring

The purpose of experiment ten was to collect data on an unknown weak acid by watching and measuring the weak acid being neutralized. This was done by using a Vernier Probe and using the data to figure out the identity of the unknown acid. A weak acid will have a strong conjugate base. The pKa of a weak acid can be taken from the – log (ka) or by using pH. To find the pKa using the graph of the pH in the experiment the equivalence point was found and ½ of this point is the pKa of the unknown weak acid. To determine the molar mass of the unknown acid the moles of base has to be determined along with the mass of the acid (Westfield, n.a). The equivalence point needed to determine the pKa is the point of the titration curve where the pH begins

Upon completion of each spot test, as well as initial pH tests, the results were then recorded. It was known that the 10 solutions consisted of 1 M hydrochloric acid, 1 M nitric acid, 3 M acetic acid, 1 M sodium hydroxide, 0.1 M silver nitrate, 0.1 M sodium chloride, 0.1 M zinc chloride, 0.1 M aluminum nitrate, 3 M ammonium hydroxide and 0.1 M lead nitrate, however their corresponding number was unknown. The first identified unknown was 98, acetic acid, given its highly prevalent scent, in addition to it not forming a precipitate with any substance due to the solubility rules. Given that two bases were present on the initial pH test, one being strong (93) and one being weak (91), it was then concluded that they were the strong base NaOH and the weak base NH4OH, respectively. Once identified, the precipitates formed by these two bases were then taken into account. Given that both bases reacted with the weak acid, 99, yet it drastically different manners (white and copper), it was then researched to see what would react with these bases to form a copper colored precipitate, resulting in AgNO3. Given that this was only one reaction, 99 as AgNO3 was not a fully supported result yet; further reactions would have to be considered. Next, the chemical reactions were written out to determine

A mixture of thiamine hydrochloride (3.5 g, 0.01 moles), and deionized water (10 mL, 0.555 moles) was added into a 100 mL round bottom flask, and swirled until the thiamine hydrochloride had dissolved. Ethanol (30 mL, 0.521 moles) and 2 M sodium hydroxide (10 mL, 0.27 moles) were added to the flask, swirled in, and cooled in an ice bath for 4 minutes. Upon removal from the ice bath, the flask was gently heated by reflux for 30 minutes.

For a long time, consuming antacids to cure acidity or the acid reflux (http://www.joybynature.com/collections/acidity) has been the only case. With the onset of health concerns and the problems that people faced with the chemicals

bstract: This lab explored the effectiveness of various antacid tablets in regard to Sodium Bicarbonate. The effectiveness of the antacid tablet was measured by how much NaOH was added to the antacid and HCl solution, and the results indicated that the brand name product consumed 0.00391 mol of HCl compared to the off brand product that consumed 0.00250 mol of HCl which shows that the name brand product was a better antacid. Introduction: In this experiment, two different types of antacid tablets is used to determine which one is more effective.

The results of all three concentrations all increased with time. The 30 percent concentration resulted in 2.08g at ten minutes, 3.14g at 20 minutes, 4.10 at 30 minutes, 5.11g at 40 minutes, 6.18g at 50 minutes, 6.97 at 60 minutes, 7.78 at 70 minutes, 8.42 at 80 minutes and 8.87 at 90 minutes. You can see all these results and data for 30 percent concentration in table xxx. Making the osmotic rate for 30 percent concentration 0.095g/mL. For the 20 percent concentration, at 10 mintues is was 0.60g, 0.93g at 20 minutes, 1.44g at 30 minutes, at 40 minutes is was 1.95g, 2.34g at 50 minutes, 2.60g at 60 minutes, 3.02g at 70 minutes, 3.44g at 90 minutes, and 3.38 at 90 minutes. The data for 20 percent concentration equals to a osmotic rate of 0.039g/mL.

Heartburn is generally caused by imbalanced gastric juices/acids. Antacids are a type of medication, which corrects the pH balance in your stomach. A pH scale is a scale that ranges from 0-14, with 0 being the most acidic, 7 being neutral, and 14 being most basic. There are many types of antacids, such as sodium bicarbonate (contains baking soda), calcium carbonate, there is also aluminum and magnesium based antacids. A combination of aluminum and magnesium based antacids also exist. These come in liquid and solid tablet forms. The brands, which are going to be tested during this experiment, will be milk of magnesia by the Life Brand that costs $8.99; Phillips that costs $13.99, and Bismuth by the Life Brand that costs $5.99.

The build up of stomach acid may cause irritation and excess pain to individuals. Luckily, antacids being a weak base can help relieve the symptoms and pain. Antacids, such as Gelusil, Medi-Firs, Alka Seltzer, and Alcalak are neutralizing agents of acids that become helpful to the human body when heartburn occurs. Heartburn, also known as acid reflux is a common medical issue that occurs when hydrochloric acid (HCl) from the stomach moves backward along the digestive track to the esophagus (located within the throat). This reverse flow of fluids causes a burning sensation due to and possible sour taste that is characteristic of acids [1].

Eating massive meals or lying down right when a meal. These are other common risk factors for acid reflux disease being overweight or rotund, eating a significant meal and lying on your back or bending over at the waist, snacking near time of day, eating sure foods, like citrus, tomato, chocolate, mint, garlic, onions, or spicy or fatty foods, Drinking sure beverages, like alcohol, effervescent drinks, coffee, or tea, Smoking, ad Being pregnant. Taking Empiric, ibuprofen, sure muscle relaxers, or force per unit area medications in several cases, life style changes combined with over-the-counter medications area unit all you would like to regulate the symptoms of acid reflux unwellness. Antacids, like gastric antacid, Maalox, Mylanta, Rolaids, or Riopan, will neutralize the acid from your abdomen. However they will cause looseness of the bowels or constipation, particularly if you overuse them. It is best to use antacids that contain each cathartic and hydrated aluminum oxide. once combined, they will facilitate counteract these duct facet effects. If antacids do not facilitate, your doctor might strive alternative

An acid-base titration is the determination of the concentration of an acid or base by exactly neutralizing the acid/base with an acid or base of known concentration. This allows for quantitative analysis of the concentration of an unknown acid
