Interpretation Introduction

Interpretation:

The $\text{pH}$ curve for the titration of a weak acid $\left(\text{HA}\right)$ with a strong base $\left(\text{NaOH}\right)$ to be sketched and the major species present in the solution are to be stated. The calculation of $\text{pH}$ at the halfway point and at the equivalence point is to be explained.

Concept introduction:

Titrations are recorded with a help of various titration curves, in which the volume of the titrant (known solution) is taken as an independent variable and the $\text{pH}$ of the solution is considered to be the dependent variable as it changes on basis of the composition of the involved two solutions.

To determine: The $\text{pH}$ curve for the titration of a weak acid $\left(\text{HA}\right)$ with a strong base $\left(\text{NaOH}\right)$ and the major species present in the solution; the calculation of $\text{pH}$ at the halfway point and at the equivalence point.
