(D) Molten sodium chloride​

Answer 1

Required Answer:-

Q//. Through which of the following does electric current not flow ?

• (A) Solution of hydrochloric acid
• (B) Copper wire
• (C) Solid sodium chloride ✓
• (D) Molten sodium chloride

Explanation:-

• Solution of Hydrochloric acid is an electrolyte because HCl is an acid. The ions can flow easily through the solution and current can pàss through$.$
• Copper is a good conductor of electricity and used in making wires and appliances.
• Molten sodium chloride also contains free ions to let the current påss through.
• The only one, Solid sodium chloride will not allow current to pàss through. Because there is no free ions or electrons to let the current pàss.

Answer 2

Required Answer :-

$\large \sf \checkmark Option \: C$

Know more :-

Copper is an conductor because it allow current to flow through it. There will be the flow of current. Also solution of hydrochloric will form an acid. Also molten sodium chloride will allow the flow of current.

Therefore

We remain with only one option. Option C. Hence option C is correct
