Textbook Problem

A solution is 0.030 M HNO3 (nitric acid). What is the hydronium-ion concentration at 25°C? What is the hydroxide-ion concentration at 25°C?

Interpretation Introduction

Interpretation:

The concentration of hydronium ion and hydroxide ion at 25°C has to be determined.

Concept introduction:

The concentration of hydroxide ion or hydronium ion concentration is calculated by using the following formula.

[OH-] = Kw[H3O+] 

Where,

Kw for an acid is 1.0×10-15M

Kw for an base is 1.0×10-14M

Explanation

The given solution is nitric acid and it is strong acid.

We know that, the given concentration of nitric acid is equal to hydronium ion concentration.

 So, the concentration of hydronium ion is [H3O+] = 0.030 M 

Now, let’s calculate the concentration of hydroxide ion by using the following formula

[OH-] = Kw[H3O+] 

Substitute the values in the above equation and do some simple mathematical calculation to get hydroxide ion concentration as follows
