Normal water is mainly protium oxide, H(...

Normal water is mainly protium oxide, `H_(2)O` However, if protium atoms in normal water molecule are replaced completely by deuterium atoms, the resulting water is called heavy water.
The ionization constant of protum water `(H_(2)O hArr H^(+)+OH) is 1xx10^(-14)` and that in heavy water `(D_(2)O hArr OD^(-)) is 3xx10^(-15) is 3xx10^(-15) H_(2)O` dissociates about

A

three times as much as `D_2 O `does

B

thirty times as much as `D_2O` does

C

0.3 times as much as `D_2O` does

D

300 times as much as `D_2O` does

Text Solution

Verified by Experts

The correct Answer is:
A
`((K_w)_(H_2O))/((K_w)_(D_2O)) = (1 xx 10^(-14))/(3 xx 10^(-15)) = 10 /3 = 3.333`
