Question

Which of the following acids is a weak electrolyte?

• A. $H_{2}C{O}_3$
• B. $C{H}_{3}COOH$
• C. Both A and B
• D. None of the above

Answer 1

Answer: (C)

Both A and B

When the acid $H_{2}C{O}_3$ and $C{H}_{3}COOH$ are dissolved in water, it undergoes partial dissociation to form the ions $H^{+}$ and $HC{O}_3^{-}$ and $C{H}_{3}CO{O}^{-}$ ions.

Since there is partial dissociation so both are weak acids and hence weak electrolyte.
