27.3 ml sample of a 0.488 m aqueous hydrofluoric acid solution is titrated with a 0.367 m aqueous potassium hydroxide solution. what is the ph at the start of the titration, before any potassium hydroxide has been added?

The pH of the solution when no base is added is 0.311

Explanation:

The chemical formula of hydrofluroic acid is HF. It is a monobasic acid.

1 mole of HF produces 1 mole of hydrogen ions and 1 mole of fluoride ions.

To calculate the pH of the solution when no base is added, we use the equation:

We are given:

Putting values in above equation, we get:

Hence, the pH of the solution when no base is added is 0.311
