Answer: under aqueous or molten state
Step-by-step explanation:
An ionic compound is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal.
is an ionic compound.
Ionic compounds do not conduct electricity in solid state as ions are not available for conduction of electricity. When
is in molten form or aqueous state, it gets converted to ions
and
and hence help in conduction of electricity.
