Question

HCl is covalent compound, yet its aqueous solution conducts electricity. Why?

Answer 1

Dear Student

HCl being a covalent compound is still a polar compound and polar compounds dissociates into anion or cation in their molten state or aqueous solution by accepting or donating electron respectively.

Here, chlorine being more electronegative accepts electron that is being given by the hydrogen in the aqueous solution to become Cl^- and H⁺ respectively. These charged species conduct the electricity in the aqueous solution of HCl.
