Purpose: The purpose of this experiment was to test the effectiveness of Tums verses the generic products. To make this happen we used a technique called titration. This experiment also helped in our exploration of mole ratios by figuring out how many moles of acid were neutralized by each antacid tablet. Procedure: To start off the experiment we had to make a dilute solution. To do this we gathered 50mL of 1.0M stock solution of HCL in an Erlenmeyer flask. Then using a volumetric pipet we transferred 25mL of the stock solution to a 100 mL volumetric flask. Then we filled the rest of the volumetric flask, up to the 125mL mark, with water. Next we capped the volumetric flask and flipped it upside down several times to stir up the solution. After the dilute solution was made we then neutralized it with the antacids. First we weighed the Tums tablet and the generic tablet. Then in two separate mortars we crushed up the two tablets into powders. We then weighed out .20 grams of the Tums tablet and then put it in a new Erlenmeyer flask. Once again we used the volumetric pipet to transfer 25 mL of the dilute HCL solution into the Erlenmeyer flask with the Tums. Swirl the flask around to dissolve the tablet. After this we begin the titration process of the experiment.
