Titration of a Commercial Antacid
inaccurate results. Therefore it is important to boil the solution when the carbonate reacts with acid, to remove CO2 as a gas. Procedure: You will work in pairs, but each student should perform one of the titrations. 1. In a 125 mL Erlenmeyer flask, pipet in exactly mL of _____M HCl. You will be using a mL pipet. 2. Take 1 tablet of Tums.
