=**THE STUDY OF ALKA-SELTZER TABLETS DISSOLVING IN DIFFERENT LIQUIDS **= **Coleman M.** **2011-2012**

The purpose of this study was to find the pH of the selected liquids, then determine which of those liquids would dissolve an Alka-Seltzer tablet the fastest. Alka-Seltzer is made of aspirin, citric acid, and sodium bicarbonate. The method of the most important experiment was to find how fast each liquid could dissolve one Alka-Seltzer tablet. The results for that experiment turned out that water dissolved the Alka-Seltzer fastest, with ginger ale second, 7up third and sprite last, and for the rest of the experiments done, this order was repeated frequently. Mostly, the hypotheses for the experiments were correct. The most important data would be how fast the tablets were dissolved because that was what all of the follow-up experiment were based off of.
 * ABSTRACT **


 * CONCLUSION **

The most important part of the data was that ginger ale was the most acidic of all the liquids, and water dissolved the Alka-Seltzer tablet faster than any of the other liquids. Ginger ale though did dissolve the Alka-Seltzer tablets faster than any other soda. The hypothesis of which liquid would dissolve the Alka-Seltzer tablet fastest was incorrect. The hypothesis was that ginger ale would dissolve the pill fastest because of its pH level, but water did and ginger ale was second. Some future follow-up experiments could include… Water, sprite, ginger ale and 7up mixed together, and tested dissolving an Alka-Seltzer tablet. Or, another one would be to check the pH of the liquid after it dissolves a tablet, and see which liquid’s pH changed the most after dissolving a tablet.
