Chapter 18, Problem 18.172P

(a)

Interpretation Introduction

Interpretation:

Deposition of sulfuric acid in kilograms has to be calculated.

(b)

Interpretation Introduction

Interpretation:

The number of compounds of ${\text{ CaCO}}_{\text{3}}$ has to be calculated for neutralizing the acid.

Concept introduction:

Balancing reaction:

Balanced reaction is a chemical reaction in which number of atoms for each element in the reaction and the total charge are same on both reactant side and the product side.

Steps in balancing the information

• Step 1: Write the unbalanced equation
• Step 2: Find the coefficient to balance the equation.
• The coefficient should be reduced to the smallest whole number.

(c)

Interpretation Introduction

Interpretation:

The $\text{pH}$ has to be calculated.

Concept introduction:

Molarity solution can be calculated by using following formula,

  $\text{Molarity =}\frac{\text{Moles of solute }}{\text{Liters of solution}}$

$\begin{array}{l}{\text{Acid - dissociation constants can be expressed as pK}}_a\text{ values,}\\ {\text{pK}}_a{\text{ = -log K}}_a\text{ and}\\ {\text{10}}^{{\text{ - pK}}_a}{\text{ = K}}_{\text{a }}\end{array}$
