Question

name three type of substance in which an electric current can produce a chemical effect.

Answer 1

NaCl solution
Water containing small amount of sulphuric acid
AgCl solution

Answer 2

The substances which are conduct the electricity called conductors and substances which are not conduct the electricity called insulators.

Explanation:

• All most all metals are good conductors of ‘heat and electricity’. Wood is best example for insulator.

• The chemicals which are produce ions are conducts the electricity.
• For example copper sulphate solution conducts electricity because it produce $\mathrm{Cu}^{2+} and S O_{4}^{2-}$

• But “aqueous solution of glucose” does not conduct electricity because it doesn’t produce ions.

• The three type of substance in which an electric current can produce a chemical effect are aqueous NaOH, $\mathrm{H}_{2} \mathrm{O}$ and aqueous $\mathrm{CuSO}_{4}.$
