Textbook Problem

A solution of barium hydroxide at 25°C is 0.125 M Ba(OH)2. What are the concentrations of hydronium ion and hydroxide ion in the solution?

Interpretation Introduction

Interpretation:

The concentration of hydronium ion and hydroxide ion in the solution has to be determined.

Concept introduction:

Strong acid:

According to Arrhenius theory, a compound or a substance which completely ionized in a aqueous solution to give a hydronium ion and anion is said to be strong acid.

Strong base:

According to Arrhenius theory, a compound or a substance which completely ionized in a aqueous solution to give a hydroxide ion and cation is said to be strong base.

Explanation

We know that, Ba(OH)2 is a strong base and it ionizes completely in water and the reaction can be represented as follows.

Ba(OH)2(s)Ba2+(aq) + 2OH(aq)

From the above reaction, we can say that for every Ba(OH)2 which dissolves two OH- ions result.

We know that, Kw[H3O+] [OH] = 1
