1) Calculate the hydrogen ion concentration and the pH of the solution formed when 0.020 gram-formula weight of nitric acid is added to one liter of aqueous 0.20 M ammonia solution. Assume no significant volume change upon addition of the acid.
2) Calculate the molar concentration of acetic acid at equilibrium in an acetic acid solution that is 1.1% ionized.
3) Given a pure 0.50 M of HCN solution, calculate the volume that when diluted to a total volume of 70.0mL will yield a pH that is 0.65 unit higher than that of the given solution. Consider the volumes of the original solution and of the diluent to be precisely additive.
4) Calculate the pH of 0.0013 M of NaCN.
5) Calculate the pH of a solution which is 0.092 M in acetic acid and 0.092 M in sodium acetate.
6) Calculate the pH of a mixture of 50mL of 0.10 M ammonium hydroxide and 51mL of 0.10 M of HCl.
