What is Cr in K2Cr2O7?

So, two chromium atoms have an oxidation number of +12. So one chromium atom will have an oxidation number of +12 /2=+6. So oxidation number of Cr in K2Cr2O7 is +6. Hence in the molecule potassium exhibits an oxidation state of +1, oxygen exhibits an oxidation state of -2 and chromium exhibits an oxidation state of +6.

What is the anion in K2Cr2O7?

Potassium Dichromate
Potassium Dichromate molecules feature two ionic bonds between the two positively charged potassium cations and the dichromate anion, which holds a charge of -2. The dichromate ion features two chromium atoms that are bonded to four different oxygen atoms.

What does K2Cr2O7 do in organic chemistry?

Potassium dichromate is a potassium salt that is the dipotassium salt of dichromic acid. It has a role as an oxidising agent, an allergen and a sensitiser. It contains a dichromate(2-). Potassium bichromate appears as orange red crystals.

How to find the oxidation number of CR in K2Cr2O7?

So oxidation number of Cr in K 2 Cr 2 O 7 is +6. Hence in the molecule potassium exhibits an oxidation state of +1, oxygen exhibits an oxidation state of -2 and chromium exhibits an oxidation state of +6 Was this answer helpful? 4.5 (10)
