C. carbonic acid

D. salt (NaCl)

Answer 1

Answer:

C carbonic acid and D salt are the example of electrolytic solution.

Explanation:

Carbonic acid is an weak electrolyte because in aqueous solution carbonic acid undergo partial hydrolysis to generate H+ and HCO3- ions.

    H2CO3 ⇄ H+  +  OH-

NaCl is a strong electrolyte  because in aqueous solution NaCl undergo hydrolysis to generate Na+ and Cl- ions.

   NaCl ⇄ Na+ and Cl-
