Percent by Mass of Naco3 in Alka-Seltzer

In a more detailed way, hydrochloric acid at room temperature is the smallest temperature in the experiment, so it should dissolve Alka Seltzer tablets within a slowest time. Likewise, the hottest hydrochloric acid sample should dissolve the tablet in a fastest way.

There might have been more KOH solution added to the flask resulting in the observations to be wrong.

The purpose of this experiment was to mix Alka-Seltzer with Hydrochloric acid in order to analyze Sodium Bicarbonate as an active ingredient in the Alka-Seltzer. The mixture will contain hydrochloric acid to only see the composition of Sodium Bicarbonate in the tablet once it reacts. The amount that reacted allowed us to determine how much of it is present in the tablet. The amount of sodium bicarbonate will be measure by using the ideal gas law PV=nRT. The experiment will be conducted in the lab, therefore we are going to use room temperature which ranges from 15 to 26 degrees celsius. At room temperature pressure ranges from 12.8 to 25.0 millimeters mercury according to its corresponding room temperature.In the ideal gas equation R is 0.08206latm/mol k which is a constant. Once we have those values we can calculates the number of moles that reacted in the mixture by solving for the missing value. With the number of moles we are able to find the mass in grams which is what will potentially tell us the composition of Sodium Bicarbonate in a tablet of Alka-Seltzer.

Alka seltzer acts as an antacid. It uses sodium hydrogen carbonate to neutralise excess hydrochloric acid in the stomach and thus relieves heartburn.

Lastly, the water that the beakers were washed with may have steadily lowered the temperature of the glass throughout the trials and therefore affected the base temperature of the vinegar and the temperature of the

Alka Seltzer is a medicine that acts as a pain reliever and an antacid. Antacids are used to help neutralize the acids in the stomach and help treat acid reflux, heartburn, indigestion, and gastritis. The tablets contain sodium bicarbonate (NaHCO3) and citric acid (C6H8O7). The sodium bicarbonate is a base that helps neutralize the acids in the stomach, mainly hydrochloric acid (HCl). It does this by the following reaction: Na3C3H5O7(aq) + 3HCl(aq) H3C3H5O7(aq) + 3NaCl(aq). When the tablets are dropped into the water, a reaction occurs in which water (H2O), sodium citrate (Na3C6H5O7), and carbon dioxide (CO2) are formed.

Alka Seltzer is a medical drug used for pain relief and used for relieving indigestion. For example, if you have a stomachache or some indigestion problems, Alka Seltzer may help neutralize the stomach acidity. Not only that, Alka Seltzer is also used for cleaning household items, such as vases or jewelry. Alka Seltzer contains citric acid and sodium bicarbonate, which makes it dissolve and release carbon dioxide gas when dropped in water. In this experiment, my lab partner, Rebecca, and I are trying to find a way to make Alka Seltzer dissolve faster in water. Rebecca and I both decide that if we increase the temperature of the water or make the water hotter, then the Alka Seltzer will dissolve faster because I know when salt and sugar dissolve in hot water, they dissolve faster. I predict that this same result would apply to this experiment.

Introduction: Alka-seltzer contains three active ingredients, aspirin, sodium hydrogen carbonate and citric acid. It is used for headaches, migraines, and cold and flu symptoms. Alka-Seltzer is usually taken when dissolved in a glass of water. When placed in water a series of chemical reactions result into Sodium citrate and Sodium acetylsalicylate. The sodium citrate would act as the antacid for stomach pains, and the sodium acetylsalicylate would act as the pain reliever.

An Alka Seltzer is a white, solid, odorless tablet that is used in our daily life. For the most part it is mainly used for temporary relief on heart burns, acid indigestion, upset stomachs, headaches and pain in general. The purpose of the lab conducted was to show the fastest way on can dissolve an alka seltzer tablet using different liquids. The liquids used were regular tap water, Sprite and Minute-Maid Apple Juice. So, if we use different types of liquids to see which will dissolve the alka seltzer the fastest, then out of the three liquids water will take the least amount of time to fully dissolve the tablet because it is the most recommended liquid to take with any

was to determine the percentage by mass of acetic acid in vinegar using acid/base titration. The

We had two bottles, we filled one bottle with CO2 from the Alka-Seltzer tablets. The other bottle we left alone. We then placed both of the bottle under a 92 Watt light bulb heating the two bottles. The bottle with the CO2 from only 1 tablet only rose about 2 degree Celsius. Which was the same for the bottle without CO2. We then used two Alka-Seltzer tablets, and the temperature rose about 3ᐤ C. When we dropped three tablets, the max temperature risen in 5 minutes was 4ᐤ C. The more tablets we dropped the higher the temperature becomes.

The second data table provides the results of all the brand antacids, including Medique Alcalak and Alka Seltzer, and the average of Gelusil. The results also include the initial moles of HCl used, average volume of NaOH used, moles of NaOH used, and moles of HCl neutralized by antacid. In the experiment, according to the data, the Medique Alcalak neutralized the most moles of HCl while the generic antacid followed suit. Then, the Alka-Seltzer neutralized the second least amount of HCl followed by Gelucil. As a note, because two groups were assigned to the Gelusil brand antacid to run their own trials and calculations, the class was instructed to calculate the average of their results. Furthermore, there was a substantial difference between the two results and the difference can be attributed to the differing amount of mL NaOH they may have used to titrate with. Additionally, a rough trial was performed during our experiment which ended up providing an opportunity to see how much NaOH was needed for titration before it became purple and too basic. The group named this the rough trial as we recorded the largest possible amount of NaOH used to make the solution to basic, 6 mL, and used that as a benchmark for the future so that the rest of the trials will be successful. Likewise, the trials recorded were more precise as the titration method was performed much more

The retained solution from the NaHCO3 extraction was used to precipitate the P-toulic acid. Drop wise 3M HCl was added to the extracted solution carefully until no more precipitate was formed and the solution tested acidic, with a pH reading less than 3 as indicated by pH paper testing. A piece of clean filter paper was then weighed and the mass recorded in a lab notebook. A vacuum filtration system was constructed with a Buchner funnel

(Reaction between sodium hydroxide and solution of vinegar, which produces an aqueous solution of sodium acetate and water)

Our testable question was, what is the effect of different liquids on the dissolving rate of the alka seltzer. To answer this question we dissolved alka seltzer in three different liquids, and recorded the data we found. After testing water three times
