If anyone has got their test back, could you please solve the question about deprotonation of H2O? Or if you remember how you did it, please answer.

I think for that one you had to solve for the Kw value at the lower temperature and then take the square root of that value to find the H+ concentration. If that value was lower than 10^-7 (which is the H+ concentration at pH of 7) then I think your solution was acidic because you had more H+ than OH- and vice versa.

There is an equation on the equations sheet that had both initial temperature as well as the second temperature. You would plug in the information to find the H+ concentration.
