Chapter 4, Problem 88E

(a)

Interpretation Introduction

Interpretation: The balanced chemical equation for the reaction between $\text{Sr}{\left(\text{OH}\right)}_{\text{2}}$ and ${\text{HNO}}_{\text{3}}$ .

Concept introduction:
A balanced chemical equation is based on the law of conservation of mass for a closed system. According to this law, the mass of the products formed in a chemical reaction is equal to the mass of the reactants involved in the reaction.

(b)

Interpretation Introduction

Interpretation: The concentration of each ion that remains in the solution.

Concept introduction:
Molarity is defined as the ratio of number of moles of solute to the volume of the solution in liters.
$\text{Molarity}=\frac{\text{Moles}\text{of}\text{solute}}{\text{Volume}\text{of}\text{solution}}$

(c)

Interpretation Introduction

Interpretation: The resulting solution is acidic or basic.

Concept introduction: Solution is said to be basic, when ${\text{OH}}^{-}$ ions are present in the solution in excess amount.
Solution is said to be acidic, when H+ ions are present in the solution in excess amount.
