Purpose:

The purpose of this investigation is to test different antacids - mild base that can neutralize acid - for their effectiveness in neutralizing stomach acids, to see if all antacid tablets are equally effective, and to learn the way of comparing antacid tablets in their acid- neutralizing ability to baking soda.

Hypothesis/ Prediction:

The most effective antacid will be Gaviscon and the least effective one will be Alka-Seltzer. All antacid tablets will not be equally effective.
