Question
Which of the following reaction is redox?
Options
A.$Mg_{3}N + 6H_{2}O \rightarrow 3Mg(OH)_{2} + 2NH_{3}$
B.$CaC_{2} + 2H_{2}O \rightarrow Ca(OH)_{2} + C_{2}H_{2}$
C.$Ca(OCl)Cl + H_{2}O \rightarrow Ca(OH)_{2} + Cl_{2}$
D.$PCl_{5} + 4H_{2}O \rightarrow H_{3}PO_{4} + 5HCl$
Solution
In Ca(OCl)Cl, the oxidation state of ‘Cl’ is +1 and –1 but in the product Cl2, it becomes zero.
