Question

what is the oxidation of Cr in Cr2(So4)3

Answer 1

Cr2(SO4)3
2x+3 (-2)=0
2x=6
X=+3
Oxidation state of cr is +3

Answer 2

Hello friend !!!

Here's the answer you are looking for

Let us consider the oxidation number of Cr is x

Since Cr2(SO4)3 is a molecule, it's oxidation number is 0.

And the oxidation number of (SO4) is always -2.

So, mathematically,

2x + 3(-2) = 0

2x = +6

x = +3

Therefore, the oxidation number of Cr in Cr2(SO4)3 is +3.
