This experiment was conducted to find out how effective different types and brands of antacids are at neutralizing acid. The experiment was done using 4 brands of antacid.
1. For this experiment, the independent variable is the brand of antacid. The dependent variable is the amount of acid needed to neutralize the antacid. This is determined by measuring the amount of acid dropped from the burette, and by using a pH meter. The constants (control variables) are the concentration of acid solution and the amount of water in the beaker. 2. The 4 beakers are filled with 200ml of water each. Using the marker pen, the 4 beakers are labeled Magnesia, Gaviscon, Turns and Tagamet. 3. The recommended dosages of the 4 types of antacids are mixed together .....
