DEN Solving a redox titration problem To measure the amount of calcium carbonate (CaCO) in a seashell, an analytical chemist crushes a 3.60 g sample of the shell to a fine powder and titrates it to the endpoint with 202. mL of 0.2800 M hydrogen chloride (HCl) solution. The balanced chemical equation for the reaction is: 2HC1(ag) + CO (aq)- H2CO3(aq)+ 2CI (aq) precipitation x10 What kmd of reaction is this? acid-base redox said this was a precipitation reaction, enter the chemical formula of the If you precipitate. If you said this was an acid-base reaction, enter the chemical formula of the reactant that is acting as the base. If you said this was a redox reaction, enter the chemical symbol of the element that is oxidized. Calculate the mass percent of CaCO, in the sample. Be sure your answer has 3 0% significant digits.
