The OH- concentration of 0.050 M ammonia, NH3, is 9.5x10^-4. Write the equilibrium equation for its ionization and the equilibrium constant expression; solve for the value of K.

Answer 1

NH3 + HOH ==> NH4^+ + OH^-

Kb = (NH4^+)(OH^-)/(NH3)
Set up an ICE chart and substitute into the Ka expression. Solve for Kb.
