Question

i Was able to calculate the initial pH which is 9.50 but i'm having trouble calculating pH after addition of NaOH

Solution C is made by mixing 57.9 mL of 0.16 M ammonium chloride (NH4Cl) with 60.4 mL of 0.26 M ammonia solution. pKa (NH4+) = 9.24

(a) Calculate the pH of Solution C.

(b)Calculate the pH of the buffer Solution C if 0.13 g of NaOH (molar mass = 40.0 g/mol) is added (assuming no change in volume).
