Chapter 16, Problem 45PE

Interpretation Introduction

Interpretation:

Concentration of hydrogen ions and $\text{pH}$ for a buffer solution of ${\text{HC}}_2{\text{H}}_3{\text{O}}_2$ and sodium acetate $\left[{\text{H}}^{\text{+}}\right]$ has to be calculated.

Concept Introduction:

The species formed by dissociation of acid into ions with a loss of hydrogen ion is termed as conjugate base. It has power to accept proton in a reaction.

Solution that causes resistance in change of $\text{pH}$ due to dilution or addition of acid is termed as buffer solution. Two types of buffer solutions are as follows:

1 Weak acid mixed with salt of its conjugate base

2 Weak acid mixed with salt of its conjugate acid
