Vedclass · Answer

(C) The given salt $CH_3COONa$ is a salt of a weak acid $(CH_3COOH)$ and a strong base $(NaOH)$.For such a salt,the concentration of $[H^{+}]$ is given by the formula:$[H^{+}] = \sqrt{\frac{K_w 	imes K_a}{C}}$Given:$K_w = 10^{-14}$$K_a = 10^{-5}$$C = 0.1 \, M = 10^{-1} \, M$Substituting the values:$[H^{+}] = \sqrt{\frac{10^{-14} 	imes 10^{-5}}{10^{-1}}} = \sqrt{10^{-19} 	imes 10^{1}} = \sqrt{10^{-18}} = 10^{-9} \, M$

The concentration of $[H^{+}]$ in a $0.1 \, M \, CH_3COONa$ solution [$K_a = 10^{-5}$] is equal to ......
