## Buffer calculations

1. The problem statement, all variables and given/known data
Buffer solution : CH_3COOH (55 mL) + CH_3COONa (45 mL)
Ka (CH_3COOH) = 1.76 x 10^-5

Calculate the expected pH of your buffer solution after it has been dilted by making 10 mL of buffer up to 100 mL with deionized water.

2. Relevant equations
Ice charts
n= c x v
c= n/v

3. The attempt at a solution
I've calculated the pH for other additions of strong acids and strong bases but I'm not sure how to start this one. Little bit confused... Just the first step would be a great help :)

 Recognitions: Gold Member Homework Help Science Advisor You haven't given enough information to start. You need to know something about the concentrations of acetic acid (55 mL?) and acetate (45 mL?).
 Sorry, they are both 0.10 M
