Question

Which of the reagents listed below could be added to water to make 0.1 M solutions of $C{H}_{3}CO{O}^{⊝}$ ions?
i. $C{H}_{3}COOH$ ii. $C{H}_{3}COONa$

• A. $C{H}_{3}COOH$ because it is a strong electrolyte
  
• B. $C{H}_{3}COONa$ because it is a strong electrolyte
  
• C. $C{H}_{3}COOH$ because it is a weak electrolyte
• D. $C{H}_{3}COONa$ because it is a weak electrolyte

Answer 1

The correct option is B $C{H}_{3}COONa$ because it is a strong electrolyte

$C{H}_{3}COONa\to C{H}_{3}CO{O}^{-}+N{a}^{+}$ --- because $N{a}^{+}$ highly soluble in water.

$C{H}_{3}COOH$ is a weak is a electrolyte, does not dissociate sufficiently
