Finding pH of solution

  1. Nov 18, 2012 #1
    1. The problem statement, all variables and given/known data
    A solution is prepared by mixing 200 mL of 0.2 M CH3COOH with 100 mL of 0.1 M of NaOH solution.Calculate the pH of the solution.(Ka=1.8x10^-5)


    I really don't know how to start this, so please help me.Its gonna be a similar one on my exam tomorrow.

    Thanks.

    Some of what you are missing is to fill in THIS information more precisely:

    2. Relevant equations and rules

    CH3OOH + NaOH ⇔ NaCH3OO + H2O

    Ka = [itex]\frac{[H][CH3OO]}{[CH3OOH]}[/itex]
