Solving a redox titration problem
DE
To measure the amount of calcium carbonate (CaCO) in a seashell, an analytical chemist crushes a 4.800 g sample of the shell to a fine powder and titrates it
to the endpoint with 345. mL of 0.2000 Mhydrogen chloride (HCI) solution.
The balanced chemical equation for the reaction is:
