I did the first question but i'm not sure the actual answer is correct as I was not given a Ka. When I searched for a Ka. I got 1.3 x 10^-5. so I got a ph of 2.37 and a % dissociation of .84%. I have also written the equation. Since part b is mainly where the trouble is, would everything be divided by 10 since it is diluted 10 fold
