pH question
« on: October 17, 2009, 09:41:09 pm »

This question was from the CSE 09 trial exam:
A lactic acid solution is at equilibrium in a beaker. The lactic acid concentration is then increased by the addition of Lactic acid. What is the effect on:
1) pH
2)OH- concentration
3) Ka

I know that the pH will decrease and no change to Ka, but what will happen to the concentration of hyroxide ions? Will it stay the same or decrease?

Thanks!

pH decrease = [OH-] decrease
