 * A STUDY OF DISSOLVING ALKA-SELTZER IN DIFFERENT LIQUIDS **

The purpose of this experiment was to test the dissolving times of Alka-Seltzer tablets in different liquids. Alka-Seltzer tablets are little round antacid tablets that are made of sodium bicarbonate, potassium bicarbonate, and citric acid. An Alka-Seltzer tablet was dropped into 100 mL of water and at the same time, a timer was started. After the Alka-Seltzer tablet dissolved completely, the time was taken and recorded. The Alka-Seltzer tablet was dissolved in three different liquids Sprite, water, or vinegar; the results showed that the Alka-Seltzer tablet dissolved the fastest in water and the slowest in Sprite. The Alka-Seltzer tablet dissolved the quickest in the water because water is the liquid that the Alka-Seltzer tablet was designed to dissolve in. Also, Alka-Seltzer tablets dissolve quicker in larger amounts of liquid compared to smaller amounts of liquid.
 * ABSTRACT **

The Alka-Seltzer ended up dissolving the fastest in water. In addition to this, Alka-Seltzer tablets dissolve quicker in larger amounts of water. This data is important because it shows that higher concentrations of carbonic acid don’t necessarily cause the dissolving time of an Alka-Seltzer to drop. The hypothesis was correct because the Alka-Seltzer tablet dissolved the fastest in water. To follow up this experiment, Alka-Seltzer tablets could be dissolved in different liquids with varying pH’s.
