Chapter 9, Problem 9.141QP

(a)

Interpretation Introduction

Interpretation:

The preparations of ${\text{Mg(OH)}}_{\text{2}}$, $\text{AgI}$ and ${\text{Ba}}_{\text{3}}{{\text{(PO}}_{\text{4}}\text{)}}_{\text{2}}$ are should be described.

Concept introduction:

Precipitation reaction:

• The precipitate is formed, when two chemical solutions are mixed together is called precipitation reaction.
• The formed precipitate is insoluble in aqueous solution mixture, that is why it is comes out in the form of precipitate to the solution.
