Ammonia (NH3) ionizes according to the following reaction:

NH3(aq) + H2O(l) ⇌ NH4+(aq) + OH–(aq)

The base dissociation constant for ammonia (NH3) is Kb = 1.8 × 10–5. Ammonia (NH3) also has a chloride salt, ammonium chloride (NH4Cl), which is soluble in water.

If 0.070 M of ammonia (NH3) and 0.035 M of its salt ammonium chloride (NH4Cl) are mixed in a solution, what is the pH of this solution?

I came up with an answer of 9.6, is this correct?

That looks ok to me.
