## Homework Statement

Kk so the problem is that we have 55.48 ml of NaOH was required to titrate 25 mL of a weak monoprotic acid. After 31.64 mL of NaOH had been added, the pH is 4.96 for the solution. Calculate the Ka and pKa for this weak acid.

## Homework Equations

pKa= pH + log(acid/conjugate base) maybe?

ka=products/reactants

## The Attempt at a Solution

I wanted to make the NaOh and acid a ratio and then since we know what pH is, just use the first equation but I don't think that'll be correct. Other than that I'm not sure how to approach this. Help will be aprreciated thanks
