Calculate the pH of the following aqueous solution:
Annette [7]

The pH of an aqueous solution that has a concentration of 0.35 M NaF and pKa for HF = 3.14 is 3.6.

<h3>How to calculate pH?</h3>

The pH of a solution refers to the degree of acidity or alkalinity of the solution. It can be calculated using the Henderson-Hasselbalch Equation as follows:

pH = pka + log ([A-]/[HA])

Where;

  • A- = conjugate base
  • HA = weak acid

pH = pKa + log([F-]/[HF])

pH = 3.14 + log(1/0.35)

pH = 3.14 + 0.4559 = 3.595

Therefore, the pH of an aqueous solution that has a concentration of 0.35 M NaF and pKa for HF = 3.14 is 3.6.
