Chapter 19.1, Problem 19.1BFP

Interpretation Introduction

Interpretation:

The pH of the given buffer solution has to be calculated.

Concept Introduction:

When the concentration of one of the ions of a chemical solution got higher, it reacts with counter charged ions and precipitated out as salt till the ion product equals solubility product is called common ion effect.

Equilibrium constant $K_a$ is given by, $K_a=\frac{\left[H^{+}\right]\left[A^{-}\right]}{\left[HA\right]}$

pH is the unit of measurment for determining the acidity or alkalinity of a solution. The mathematical definition of pH is the negative logarithm of the molar hydrogen ion concentration.

$pH=-\log \left[H_3{O}^{+}\right]$
