The oxidation state of chlorine in potassium chlorate is?
- +1
- +2
- +3
-
+5
- +7
The correct answer is: D
Explanation
- potassium chlorate --> KClO\(_3\)
valencies of K = +1, O = -2.
: (+1) + Cl + ( -2 X 3 atoms ) = 0
Cl + 1 - 6 = 0
Cl = 5
∴ The oxidation state of chlorine in potassium chlorate is +5
