The topic involves the relationship between acidic and basic solutions. Most people at one time in their lives have had stomach pain. Antacids are used to sooth your stomach (Fleishman). This project will test which antacids are the strongest. During the experiment there will be several test tubes filled with a “natural acid-base indicator” (Fleishman). Then, antacids will be dropped into each test tube. This will answer the question, “Which antacids are most potent in changing the color of the acidic solution?” The strength of an acid or base is designated by its pH on a scale of 0 to 14 (Fleishman). A pH of 7 is thought of as neutral (Fleishman). Mixtures with a low pH are acidic and mixtures with a high pH are basic (Fleishman).

The acid-base indicator will change color during this experiment when enough base (antacid) has been added to the acid to neutralize it (“Antacids/medicines”). Color change depends on the potency of the base (“Antacids/medicines“). Without the indicator, it would not be known when too much or too little base is added (“Antacids/medicines”). Total neutralization is achieved by putting together equivalent weights of acid and base (Fleishman). In a real life situation neutralization of acid is important so that the pain of heartburn is relieved (Knapp). Many people in
