Answer #1

CaCl2 is neither an acid or abase…just a neutral salt. Calcium Chloride orCaCl2 is a salt formed when Calcium Hydroxide is reacted with Hydrochloric acid and therefore it is a salt. ... Therefore, it is neither an acid nor a base. In fact, CaCl2, orcalcium chloride, is a salt.

Alkanity refers to capability of water to neuralize acid.

Alkanity is measure of capacity of solution to resist change in pH of solution

Salt increase buffering capacity hence addition of CdCl2 increased alkanity of natural water by making it more alkaline
