Why is the conductivity of ethanoic acid lower than that of hydrochloric acid at the same concentration?
Answer and explanation
Correct answer: It ionises less
Electrical conductivity in an aqueous solution depends largely on the concentration and mobility of charged particles. At the same concentration, hydrochloric acid, a strong acid, ionises almost completely and produces more ions. Ethanoic acid is weak and ionises only partially, so it supplies fewer charge carriers and conducts less electricity. It is not a base and does contain water when tested as a solution. Option A is correct.
