What chemical reaction is responsible for the endpoint observed when the NH3/NH4Cl buffer solution is titrated with HCl? Write a blanced ionic equation for the reaction.

NH3 + HCl ==> NH4Cl
So when HCl is added to an NH3/NH4Cl buffer, the NH4Cl (the salt...the acid) is increased and the NH3 (the base) is decreased. In effect, the HCl, a strong acid, is being replaced with a weak acid, NH4^+ and that is why buffers work so well.
If you prepare 1.2L of this NH4+/NH3 buffer using 0.56 mol NH3 and 1.0 mol of NH4+, what is the pH after adding a) 150mL of 1.0M HCl

I get the answer to be 8.8 for the pH. I set up a double ice table and found {OH} and then found pOH and pH. My friend got the answer to be 9.8. Who is right?
Girl no one is ever right, sometimes you gotta listen to your gut if you have one and didn't get it removed because then I am so sorry for you anyways it should most likely be none because there more to the world then checking the pH of random solutions enjoy you life before the aliens attack YOLO
