If a weak acid, HA, is 3% dissociated in a 0.25 M solution, calculate the Ka and the pH of the solution.
pH = (pKa - log[HA])/2
The Attempt at a Solution
Honestly, I'm not even sure where to start. I don't have the pH or the pKa - how am I suppose to solve for either one?
I'm really struggling with this worksheet, so I'm sure this won't be my last question.
