Answer
Dilute acid
Reason — A strong electrolyte is a substance that completely dissociates into ions when dissolved in water, allowing electric current to pass easily through the solution.
- Dilute acids, such as hydrochloric acid (HCl) or sulphuric acid (H2SO4), dissociate completely into hydrogen (H+) and corresponding anions, making them strong electrolytes.
- In contrast, sugar solution and glucose solution are non-electrolytes — they do not produce ions in water and hence do not conduct electricity.
- Ethanol in water is also a covalent compound and does not ionize, so it is a poor conductor.
Thus, among the given options, the dilute acid is considered the strongest electrolyte because it produces the maximum number of ions in solution, resulting in the highest electrical conductivity.
