Given a solution of ammonium chloride. What additional reagent or reagents are added to prepare a buffer from the ammonium chloride solution?
I know the answer is NaOH but I don't know why. Can someone explain this to me please?

Isn't ammonium chloride an acidic salt? It forms a weak acid in solution.
If I had NH4Cl, I would made a buffer by adding NH3. The NH4Cl/NH3 makes a GOOD buffer.
