Chapter 4, Problem 4.77QP

Interpretation Introduction

Interpretation:

When a solution of ${{\text{(NH}}_{\text{4}}\text{)}}_{\text{2}}{\text{CO}}_{\text{3(aq)}}$ and ${\text{CaCl}}_{\text{2(aq)}}$ are mixed, whether it forms a precipitate or not has to be given.  If it forms a precipitate, its formula has to be written.

Concept Introduction:

Precipitation reaction is a reaction in which any chemical change in a solution results in giving one or more insoluble products.  The insoluble product is called as precipitate.

The compounds that can either form precipitate or it gets soluble can be identified by the information given in figure 1.
