Chapter 16, Problem 125SAE

Interpretation Introduction

Interpretation:

pH of the given calcium chlorite solution should be calculated.

Concept introduction:

The pH is defined as the negative natural logarithm of concentration of H+ ions:

pH =-log₁₀ [H⁺]

The mathematical relationship between base dissociation constant, K_b, acid dissociation constant, K_a, and self ionization constant for water, K_w is:

${\text{K}}_b=\frac{{\text{K}}_w}{{\text{K}}_a}$

The mathematical relationship between pH and pOH is:

pH + pOH = 14
