Chapter 4, Problem 27E

Interpretation Introduction

Interpretation: The concentration of sodium ions obtained on adding $\text{70}\text{.0}\text{mL}$ of $3.\text{0}\text{M}$ sodium carbonate to $\text{30}\text{.0}\text{mL}$ of $\text{1}\text{.0}\text{M}$ sodium bicarbonate is to be calculated.

Concept introduction: A particular substance when introduced in water undergoes dissociation into its respective ions. The ion’s concentration entirely depends on the substance’s concentration in solution. The ion’s concentration is obtained by dividing the moles of ion given on dissociation with the solution’s volume.
