Which of the following statement is /are correct

Answer»

Ionic compound are LESS soluble in `D_2O" than "H_2O`
The temperature of maximum density of `H_2O` is less than that `D_2O`
Deuterium compound, can be prepared by exchange reaction where deuterium is exchange for hydrogen under SUITABLE conditions
`D_2O` has more `K_a` than that of water

SOLUTION :a) Ionic compounds are less soluble in `D_2O` than `H_2O`
b) The temperature of maximum density of `H_2O` is less than that of `D_2O`
c) Deuterium compound, can be prepared by exchange reaction where deuterium is EXCHANGES for hydrogen under suitable condiition.
