Does Antenteacids Work As Well?

You find a sample of a solution that has a faint odor resembling vinegar. You are verifying that it is indeed vinegar and you add a few drops of phenolphthalein. The sample turns pink. What assumptions can you make about this sample?

4. Both test tubes appear red with the acetic acid with the methyl orange. This indicates that the equilibrium lies toward the acid.

3.0g of salicylic acid was weighed then 3.0mL of acetic anhydride and 6 drops of 85% H3PO4 were added to it. The mixture was warmed over a water bath for 5 minutes while stirring. After warming, 20 drops of distilled water was slowly added. 15mL of water was added then the solution was heated until it became clear. It was allowed to cool and was placed in an ice bath until the solution becomes cloudy. Using pre-weighed filter paper, the mixture was filtered and was allowed to dry in the filter paper.

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 purpose of this lab is to investigate the composition of a compound suspected to be Panacetin, a type of pain-killer. Panacetin is typically made up of sucrose, aspirin, and acetaminophen, but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen, either acetanilide or phenacetin. Using techniques such as extraction, evaporation, and filtration, the three components will be isolated based on their solubilities and acid-base properties. Then, the percent composition of Panacetin can be deduced based on the masses of the three dried components. The

Pre-Lab: Analgesic drugs are known for reducing pain, while antiseptic drugs reduce symptoms such as fevers and swelling. However, some of these drugs can reduce both illnesses. To obtain a pure compound in these drugs, the scientist needs to separate the desired compound by taking advantage of the different physical and chemical properties. Such as; different boiling points, melting points and their solubility properties. To do this a chemist can also asses the differences between acidic and basic substances when they are added to water soluble mixtures. Within this current experiment I will asses the

By first measuring the pH levels of solution A through E with a pH meter, it gives a numeric reading to ph balance to a solution. Next, add in a natural indicator called anthocyanin made from the pigment from a red cabbage into each solution and mixed it until there is a distinct color and recorded on the chart. Finally, by looking at the result of the pH reading level that

Our first set of data or our first trial Tums had 12 drops while Rolaids had 68.On our second trial, Tums had seven while Rolaids had 75. During our third trial, we only took data for Tums and we had 7. Overall Tum's average had 8.6 drops and Rolaids had 71.5 drops to neutralize the substance. During our experiment, I noticed that Tums took fewer drops than Rolaids by a lot. I think this happened because Tums has a stronger antacid or a stronger PH while Rolaids has a lower or weaker antacid.

Although agmatine was discovered in the early 1900's, it is still not a well known substance yet. The reason for this is that most of the studies pertaining to it have only been done on animals. But very little of the research has been tried out on a group of humans. Still, the animals in the experiments had a similar DNA sequence as humans, so a lot of the information can be used as far as what effect that it has on the body. It has become crucial that people learn the facts regarding what agmatine can do because supplements containing the substance have already been put out on the market despite the lack of research that is available. So this article will discuss some of the most important aspects of this product for those who are interested in trying it.

4. Dip a strip of pH paper into the vinegar, or lemon juice, for about 2 seconds, compare with the colour chart, and record the result.

The testing of three different antacids was done during this experiment to determine, which of the three antacids is the best to stop heartburn.

Antacid provides relief in 5 to 10mins with more than 90% of antacid users satisfied and antagonist drug provides relief in 30 to 60mins. In such instance, there would be no reason for any patient to prefer Pepcid AC (if it is only treatment based) over antacid OTC when buying without a prescription. The differentiating factor of prevention claim alone would make antacid users to buy Pepcid AC and not any other antacid OTC. Also, Glaxo is also going for treatment/prevention drug. If JJM goes with treatment claim and Glaxo comes up with a treatment/prevention claim, then JJM would start to lose its market share that it gained just like what happened with Tagamet in 1983. In addition, Glaxo has a reputation of making a drug with almost no side effects and if it ends up making an OTC switch, the only way JJM could compete with Glaxo would be with both

To keep this a fair test I have made sure that the acid used is the

Introduction: The purpose of this experiment is to demonstrate an example of how to determine the unknown molarity of hydrochloric acid by titration with a base (sodium hydroxide). Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte (wekipedia). The first step will be measuring and combining water and acid (Hydrochloric acid). An indicator anthocyanin will be added to the solution to change the color to pink. Anthocyanin is a water-soluble vacuolar pigment that may appear red, purple, or blue depending on the pH
