Identify the correct statement from the following .
(i) `Eu^(2+)` and `Yb_(2+)` are reducing agents .
(ii)The electronic configuration of `Pr ^(3+) "is" [Xe]4int^(3)`
(iii) Aqueous solution of `LaCl_(3)` is colourless.

A

(i),(ii),(iii)

B

(i),(iii)

C

(i),(ii)

D

(ii),(iii)

Text Solution

Verified by Experts

The correct Answer is:
B
`Eu^(2+) ` and `Yb^(2+)` can lose electrons and form `Eu^(3+)` and `Yb^(2+)`.
So , act as reducing agents .
(c ) in the aqua solution of `LaCl_(3)` it forms colourless solution.
