Please help solve this question and show me the steps! How do you calculate the change in pH?

Calculate the change in pH that occurs when 0.020M of NaOH is added to a 250mL solution of 0.8M of HC鈧侶鈧僌鈧?and 0.732 M of NaC鈧侶鈧僌鈧? Assume that there is no volume change upon the addition of NaOH. (Ka= 1.8x10^-5 for HC鈧侶鈧僌鈧?Please help solve this question and show me the steps! How do you calculate the change in pH?
this is exactly why ur taking the regents in august
