Worked example Balancing a redox equation in acidic solution
So the 2 chromium atoms need to have oxidation numbers that equal 12 and there are 2 of them so each Cr has an oxidation number of 6 We have 6Cl minus plus 14 H plus plus Cr2O7 2 minus yields 3Cl2 plus 2Cr 3 plus plus 7 H2O And this should be our final answer So I always like to box my final answer so it just makes it easier for your

What is the Oxidation Number of Cr Cr2O72 Unacademy
The charge of Cr2O72 a polyatomic ion is equal to the sum of the oxidation numbers Because there are seven oxygen atoms in a molecule the overall charge is 2 7 14 Let x be the number of chromium atoms that have undergone oxidation x 14 2 x 14 2 x 12 The total oxidation number of two chromium atoms is 12 We can
