1. The problem statement, all variables and given/known data What is the final pH of a solution obtained by mixing 200 ml of 0.400 M NH3 with 300 ml of 0.100 M HCl? (Kb = 1.8 x 10^-5) 2. Relevant equations 3. The attempt at a solution I used an ICE table and came up with 9.68. Is that correct? Should I have used two ICE tables instead of one? The first in the one direction and the second going back in the other direction?
