If `K_(a_(1))gtK_(a_(2))` of `H_(2)SO_(4)` are `10^(-2)` and `10^(-6)` respectively then:

A

`K_(a_(1))` and `K_(a_(2))` because it is easy to abstract `H^(+)` from `H_(2)SO_(4)` and less easy to abstract `H^(+)` from `HSO_(4)^(-)`

B

`K_(a_(1))` and `K_(a_(2))` may be measured in acetic acid.

C

`K_(a_(1))` and `K_(a_(2))` are measured in `H_(2)O`.

D

the `H^(+)` ion conc of `0.01MH_(2)SO_(4)` will less than `0.02M`.

Text Solution

Verified by Experts

`H_(2)SO_(4)` is a strong acid and it completely dissociated in `H_(2)O` .Hence it `K_(a_(1))` and `K_(a_(2))` are determine in `CH_(3)COOH`.
Also `H(2)SO_(4)` is neutral while `H_(2)SO_(4)^(-)` is neutral while `HSO_(4)^(-)` because the `-ve `change has more affinity towards `H^(+)` ion .Hence choices `A` and `B` are correct while `C` is incorrect.
