Determine $$[{OH}^{-}]$$ of a $$0.050\ M$$ solution of ammonia to which has been added sufficient $${NH}_{4}Cl$$ to make the total $$[{NH}_{4}^{+}]$$ equal to $$0.100 M$$. $$[{K}_{b({NH}_{3})}=1.8\times {10}^{-5}]$$

The ionic product of water ______  if a few drops of acid or base are added to it.

In the presence of a common ion (incapable of forming complex ion), the solubility of salt _______  in solution.

Assertion: A solution of sodium acetate and ammonium acetate can act as a buffer.
Reason: A buffer solution consists of a mixture of a weak acid and its conjugate base or vice versa.
