Oxidation Number and Balancing
Chromium Oxidation States Calculation
Consider the following reactions:
NaCl+K
2Cr
2O
7+H
2SO
4→A+KHSO
4+NaHSO
4+H
2O
A + NaOH → B + NaCl + H
2O
B + H
2SO
4 + H
2O
2 → C + Na
2SO
4 + H
2O
In the product 'C', 'X' is the number of

units, 'Y' is the total number oxygen atoms present and 'Z' is the oxidation state of Cr. The value of X + Y + Z is ______ .
