A solution of volume 80.0 mL contains 16.0 mmol HCHO2 and 9.00 mmol NaCHO2.
If 1.00 ml of 12 M HCl is added to this, what will be the resulting pH?

(the only problem im having for this question is how to approach it, i know that by adding HCl the concentration of the CB would decrease and the concentration of the acid would increase, but how do you factor in the extra 1ml added because of HCL? )
