## Calculate the pH of the following solutions.a. 0.10 M NaOHb. 1.0 × 10−10 M NaOHc. 2.0 M NaOH

(a)

Interpretation Introduction

Interpretation: The pH value for the given solutions is to be calculated.

Concept introduction: The pH of a solution is define as a figure that expresses the acidity of the alkalinity of a given solution. A logarithmic scale is used on which, the value 7 corresponds to a neutral species, a value less than 7 corresponds to an acid and a value greater than 7 corresponds to a base.

The pOH of a solution is calculated by the formula, pOH=log[OH]

The sum, pH+pOH=14

To determine: The pH value for the given solution of 0.10MNaOH .

### Explanation of Solution

Explanation

Given

0.10M NaOH solution.

NaOH is a strong base. Therefore, it will completely dissociate into Na+ and OH ions.

Therefore, [OH] is 0.10M .

The pOH of a solution is calculated by the formula,

pOH=log[OH
