The seqeunce of ionic mobility in the aqueous solution is

A

`K^(+) gt Na^(+) gt Rb^(+) gt Cs^(+) `

B

`Cs^(+) gt Rb^(+) gt K^(+) gt Na^(+) `

C

`Rb^(+) gt K^(+) gt Cs^(+) gt Na^(+) `

D

`Na^(+) gt K^(+) gt Rb^(+) gt Cs^(+) `

Text Solution

Verified by Experts

The correct Answer is:
B
In aqueous solution, because of hydration the order of effective size is :
`Na^(+) gt K^(+) gt Rb^(+) gt Cs^(+)`
Greater is size lesser is mobility .
