Chapter 4, Problem 4.18QP

Interpretation Introduction

Interpretation:

The best representation diagram for combined aqueous solutions of $\text{KOH}$ and ${\text{MgCl}}_{\text{2}}$ should be given from given diagrams.

Concept introduction:

Precipitation reaction:

• If precipitate is formed, when two solutions are mixed together is called precipitation reaction.

Balanced equation:

• The balanced equation is nothing but the all ionic compounds are represented as neutral compounds using the molecular formula.
• In the balanced equation, the number of atoms for each element and total charge are equal in the reaction for in both reactants and the products sides.
