5 ml of a 0.2 M NH3 solution are added to 5 ml of a 0.1 M NH4Cl solution (Kb for NH3 is = 1.8 × 10-5). Calculate: a) the pH of the resulting solution; b) the ΔpH due to the addition of 5 ml of a 0.01 M HNO3 solution to the solution resulting from part a); c) the ΔpH due to the addition of 10 ml of water to the solution resulting from part a)
