Chapter 14, Problem 29CI

Interpretation Introduction

(a)

Interpretation:

The molarity of the KOH solution needs to be calculated.

Concept Introduction:

The acid base reaction is also called as neutralization reaction. It is a reaction of acid and base that results the formation of salt and water. The acidic and basic nature of substances can be checked with the help of pH of solution. The pH can be calculated as follows:

  $\text{pH}=-\log \left[{\text{H}}^{+}\right]$

Here, $\left[{\text{H}}^{+}\right]$ is hydrogen ion concentration.

Interpretation Introduction

(b)

Interpretation:

The concentration of hydronium ion and pH of the KOH solution needs to be calculated.

Concept Introduction:

The acid base reaction is also called as neutralization reaction. It is a reaction of acid and base that results the formation of salt and water. The acidic and basic nature of substances can be checked with the help of pH of solution. The pH can be calculated as follows:

  $\text{pH}=-\log \left[{\text{H}}^{+}\right]$

Here, $\left[{\text{H}}^{+}\right]$ is hydrogen ion concentration.

Interpretation Introduction

(c)

Interpretation:

The balanced chemical reaction between KOH and ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ needs to be determined.

Concept Introduction:

The chemical equation is said to be balanced if the number of atoms of same element are equal in both sides of the reaction arrow.

Interpretation Introduction

(d)

Interpretation:

The volume of diluted HCl solution needs to be determined.

Concept Introduction:

The molarity of the solution is defined as number of moles of solute in 1 L of the solution. It is mathematically represented as follows:

  $M=\frac{n}{V\left(L\right)}$

Here, n is number of moles, V is volume of solution in L.
