To measure the amount of calcium carbonate (caco) in a seashell, an analytical chemist crushes a 2.100 g sample of the shell to a fine powder and titrates it to the endpoint with 119. ml of 0.300 m hydrogen chloride (hci) solution. the balanced chemical equation for the reaction is 2hci(aq) + co, (aq) ? h2co3(aq) + 2a (aq). what kind of reaction is this?

This is an example of double displacement reaction.

Explanation:

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

The given chemical equation follows:

By Stoichiometry of the reaction:

2 moles of hydrochloric acid reacts with 1 mole of calcium carbonate to produce 1 mole of carbonic acid and 1 mole of calcium chloride.

Hence, this is an example of double displacement reaction.
