## Calculate the pH of each of the following solutions containing a strong acid in water.a. 2.0 ×10−2 M HNO3b. 4.0 M HNO3c. 6.2 × 10−12 M HNO3

(a)

Interpretation Introduction

Interpretation: The pH value for the given solutions of a strong acid in water 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 pH of a solution is calculated by the formula, pH=log[H+]

### Explanation of Solution

Explanation

To determine: The pH value for the given solution of 2×102MHNO3 .

The pH of the given solution is 1.7_ .

The reaction that takes place is,

HNO3+H2OH3O++NO3

A strong acid completely dissociates in water.

HNO3 is a strong acid. Hence, it will dissociate complete
