Why is hydrochloric acid more conducting than ethanoic acid at the same concentration?
Answer and explanation
Correct answer: It forms more ions
The governing concept is electrical conduction in ionic solutions. At equal concentration, hydrochloric acid ionises almost completely, producing many mobile H₃O⁺ and Cl⁻ ions. Ethanoic acid ionises only partially, so it produces fewer charge carriers. Therefore option A is correct. Conductivity is not evidence that HCl is a base, and it is soluble in water.
