Potassium trioxalatochromate (III ) is

A

`K_(3)[Cr(C_(2)O_(4))_(3)]`

B

`K[Cr(C_(2)O_(4))_(3)]`

C

`K_(2)[Cr(C_(2)O_(4))_(3)]`

D

`K_(4)[Cr(C_(2)O_(4))3]`

Text Solution

Verified by Experts

The correct Answer is:
A
` [Cr (C_(2) O_(4) )_(3) ]^(3-)`
oxidation state `+3+(-6 ) =-3`
thus ,`K_(3) [Cr (C_(2) O_(4) )_(3)].`
