Calculate the hydrogen ion concentration and the pH of the solution formed when .020M of nitric acid is added to one liter of aqueous .20M ammonia solution. Assume no significant volume change upon addition of the acid.

so if i use that equation am i suppose to get pH= 10.26 and [H
+
] = 5.5x10

pH= 10.26
Close. What pKa (or pKb) value do you use?
