Sergeu [11.5K]

Answer:

CuSO4(aq)

Explanation:

The aqueous form of copper sulfate will conduct electricity.

The Solid form will not be a good conductor.

C₅H₁₂ will not conduct electricity

CO₂ will not conduct electricity

  • Copper sulfate is an ionic compound
  • In aqueous solutions or molten forms, ionic compounds can conduct an electric current using free mobile ions as carriers.
  • This way, they are electrolytes.
  • In solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.
