pH of a Weak Acid SolutionCalculate the pH of a 1.39 mol.L–1 solution of hydrofluoric acid. The pKa of HF is 3.17.Enter your answer to 2 decimal places.
Question
Solution 1
To calculate the pH of a weak acid solution, we can use the formula for the ionization of a weak acid HA ⇌ H+ + A- and the definition of the acid dissociation constant Ka.
Step 1: Write the ionization equation for the weak acid. HF ⇌ H+ + F-
