Question

which of these is a property of a substance that is composed of atoms that are held together by ionic bonds? it can be shaped into wires. it has a low melting point. it conducts electricity when in solid form. it conducts electricity when it is dissolved in water.

Explanation:

Ionic - bonded substances dissociate in water into ions which can carry an electric current. They are brittle (not malleable into wires), have high melting points, and do not conduct electricity in solid form as ions are immobile.

Answer:

It conducts electricity when it is dissolved in water.
