Calculate the pH of a solution resulting from the mixing of 0.10 L of 0.10 M NaOH with 0.40 L of 0.025 M HF.
Ka HF = 7.2x10^-4
So I recognize that the initial concentrations of NaOH and HF are equal and as one is an acid and the other base, will drive each other until only 0.02 M of Na and F remain, but I can't figure out what to do after that.
Please don't just suggest reading my textbook until after you check the problem yourself
