Chapter 4, Problem 80QP

Interpretation Introduction

Interpretation:

The volume of NaOH required to titrate a solution of ${\text{HNO}}_{\text{2}}$ and HCl, both of which have the same molarities, will be different or the same is to be discussed.

Concept introduction:

Acid–base titrations are useful in determining the concentration of an unknown acid or a base.

The concentration of the unknown solution can be determined by titrating it with a standard solution of a known concentration.

If the volumes of the standard and unknown solutions are known then the concentration of the standard solution as well as the concentration of the unknown solution can be easily calculated.

The point where bases and acids having chemicallyequivalent amounts are completely mixed is known as the equivalence point.

The concentration of unknown solution can be calculated by the expression: ${\text{M}}_1{\text{V}}_1\text{}=\text{}{\text{M}}_2{\text{V}}_2$

Here, ${\text{M}}_1$ and ${\text{V}}_1\text{}$ are concentration and volume of standard solution, respectively, and ${\text{M}}_2$ and ${\text{V}}_2$ are concentration and volume of unknown solution, respectively.
