Question

HCl is added to a solution containing barium and calcium ions. If a precipitate is formed, what is it? A. No precipitate is formed B. Barium chloride

Answer 1

A. No precipitate is formed

Step-by-step explanation:

Hello,

In this case, since the reactions are:

`Ca^(2+)(aq)+2HCl(aq)\rightarrow CaCl_2(aq)+2H^+(aq)\\\\Ba^(2+)(aq)+2HCl(aq)\rightarrow BaCl_2(aq)+2H^+(aq)`

We evidence no formation of insoluble salts or precipitates since both calcium and barium chlorides are largely soluble in water due to the ionic bond which binds them, thus A. No precipitate is formed.

Regards.
