what is the resultig pH if 0.005 mol of NaOH is added to 100.0mL of buffer containing 0.010 mol acetic acid (CH3COOH,pKa = 4.74)and 0.010 mol sodium acetate (NaCH3COO)? (Assume the final volume is 100 mL)
So i worked it out, i just need to double check the pH. Let me know what you get, thank you.

Why don't you show what you have and how you obtained that and let US check you?
Oh, ok well i came out with a pH of 5.22. pH = pKa + log A/HA. I came up with .15M as A and .05 as HA. So 4.74+log(3)= 5.22.
Thanks. I agree.
