Chapter 4, Problem 4.154MP

Interpretation Introduction

Interpretation:

Amount of $\text{NaOH}$ and ${\text{Ba(OH)}}_{\text{2}}$ in g must be found out from a mixture.

Concept introduction:

• Acidity of base is the number of replaceable OH present in the base.
• Basicity of $\text{NaOH}$ and ${\text{Ba(OH)}}_{\text{2}}$is 1 and 2 respectively.
• 1 mole $\text{NaOH}$ and ${\text{Ba(OH)}}_{\text{2}}$ will be reacting with 1 and 2 moles of $\text{HCl}$respectively.

Given:

Total amount of mixture as 10 g which is dissolved in 250 ml water. The mmol of $\text{HCl}$ is also given.
