Which of the following (1M) conducts more electricity?

Answer»

sulphuric ACID
boric acid
nitric acid
aluminium.

Solution :More the number of ions especially smallercations (hydrated `H^(+)` ions) more the conductivity At 1 M CONCENTRATION weak acids like `H_(3)PO_(3),H_(3)BO_(3)` will be weakly DISSOCIATED resulting in poor conductivity of `HNO_(3)` and `H_(2)SO_(4)`both STRONG acis `H_(2)SO_(4)` solution will be more conducting due to larger number of `H^(+)` ions in solution.
