Question

Acetic acid dissociates as,

${CH}_{3}COOH\rightleftharpoons {CH}_3{COO}^{-}+H^{+}$. If a little amount of sodium acetate is added to its aqueous soluton then:

• A. the acid dissociates further
• B. the $H^{+}$ ion concentration increases
• C. the acid dissociation is suppressed
• D. the equilibrium is unaffected

Answer 1

The correct option is C the acid dissociation is suppressed

$C{H}_{3}COOH\rightleftharpoons C{H}_{3}CO{O}^{-}+H^{+}$

if acetate is added , the reaction goes in backward direction and acid dissociation is supressed.
