1. To prepare the 3.0 M HCl, add 250 mL of concentrated HCl to 650 mL of distilled water. Then dilute to 1.0 L using distilled water. 2. To prepare the eggshells, make sure that the inner merane is completely removed. You may want to do this as pre-lab, or
Notice the 2-to-1 mole ratio of HCl-to-base. To determine the amount of base in an actual tablet, ideally you would dissolve it in water and titrate with acid. In most titrations, solutions of the acid and the base are used. This is not an option here because CaCO 3 is …
