Solution:
Buffer solutions are obtained, when a weak acid is mixed with its conjugate base or a weak base is mixed with its conjugate acid. Hence, solution of acetic acid and sodium acetate is a Buffers solution.

A buffer solution is prepared in which the concentration of \(\mathrm{NH}_{3}\) is \(0.30 \mathrm{M}\) and the concentration of \(\mathrm{NH}_{4}^{+}\)is \(0.20 \mathrm{M}\). If the equilibrium constant, \(\mathrm{K}_{\mathrm{b}}\) for \(\mathrm{NH}_{3}\) equals \(1.8 \mathrm{x}\) \(10^{-5}\), what is the pH of this solution? ( \(\log 2.7=0.43\) )
