• question_answer 75) 1.0 mole of HCl and 1.0 mole of $C{{H}_{3}}COONa$are dissolved in water and volume is made one litre. What should be the concentration of ${{H}^{+}}$ in the solution. If ${{K}_{a}}$ of $C{{H}_{3}}COOH$ is $1.6\,\,\times \,\,{{10}^{-}}^{5}$ A) $1.6\times {{10}^{-}}^{5}$               B) $4\times {{10}^{-}}^{3}$C) $16\times {{10}^{-}}^{5}$                D) $4\times {{10}^{-}}^{2}$

$HCl+C{{H}_{3}}COONa\,\,\to \,\,C{{H}_{3}}COOH+NaCl$ Initial    1      1       0       0 Final     0      0       1      - $[{{H}^{+}}]\,\,=\,\,\sqrt{{{K}_{a}}\times C}$
