Question

Which of the following conducts electricity​

Answer 1

Explanation:

The availability of ions is very important to conduct electricity. Distilled water is a pure type of water which does not contain any ions in it. Whereas rainwater contains dissolved gasses such as SO2, CO2.

Answer 2

It seems like you are searching for" Which of the following conducts electricity?

(A) Crystalline NaCl

(B) Fused NaCl

(C) Molten sulphur

(D) Diamond

Answer:

Fused NaCl  conducts electricity.

Explanation:

• Ionic compounds in solids do not conduct electricity because their rigid structure prevents the movement of ions in solids. However, ionic compounds conduct electricity when melted. This is possible in the molten state as the heat overcomes the electrostatic attraction between the oppositely charged ions. Therefore, the ions move freely and conduct electricity.
• Molten sulphur and diamond are non-metals so  they don't conduct electricity.
