A redox reaction occurs
Given
Reaction
Ca(ClO3)2 → CaCl2 + 3O2
Required
Type of reaction
Solution
The reaction equation is said to be a redox reaction if there is an oxidation reaction (increase in oxidation number) and a reduction reaction (decrease in oxidation number)
Oxidation number of Cl in Ca(ClO3)2 :+5
Oxidation number of Cl in CaCl2 = -1
Reduction : +5 to -1
O in Ca(ClO3)2 : -2
O in O2 : 0
Oxidation : -2 to 0
So there is a reduction and oxidation reaction
