The oxidation state of chlorine in potassium chlorate is?...
The oxidation state of chlorine in potassium chlorate is?
+1
+2
+3
+5
+7
Correct answer is D
- potassium chlorate --> KClO3
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
