`Ka_(1), Ka_(2)` and `Ka_(3)` are the respective constants for the following reactions `H_(2)S hArr H^(+) + HS^(-)` `HS^(-) hArr H^(+) + S^(2-)` `H_(2)S hArr 2H^(+) + S^(2-)` The correct relationship between `Ka_(1), Ka_(2)` and `Ka_(3)` isA. `K_(a_(3)) = K_(a_(1)) xx K_(a_(2))`B. `K_(a_(3)) = K_(a_(1)) + K_(a_(2))`C. `K_(a_(3)) = K_(a_(1)) - K_(a_(2))`D. `K_(a_(3)) = K_(a_(1)) //K_(a_(2))`

Answer» Correct Answer - A
`K_(a_(3)) = K_(a_(1)) xx K_(a_(2))`
