Acid-Base reactions are a part of everyday life. In the previous lab, students identified everyday substances found in the home as acids or bases. In their second chemistry lab, the grade ten science class explored the practical applications of acid-base reactions, specifically looking at the use of antacids to stop acid reflux (“heartburn”). The antacids used were: Alka-Seltzer, Tums, Rolaids, and Life Brand.
In the experiment, the different antacids were reacted with an acid (soda pop – coke) to determine which one neutralizes the acid best (increases the pH). After the experiment, students explored the results, and reflected on the effectiveness of the antacids and considered possible explanations for their observations.
