Answer: under aqueous or molten state
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.[tex]KBR[/tex] is an ionic compound.
Ionic compounds do not conduct electricity in solid state as ions are not available for conduction of electricity. When [tex]KBR[/tex] is in molten form or aqueous state, it gets converted to ions [tex]K^+[/tex] and [tex]Br^-[/tex] and hence help in conduction of electricity.
