Find out the oxidation state of sodium in `Na_(2)O_(2)`

Text Solution

Verified by Experts

Let the oxidation state of sodium in `Na_2O_2` be x. `Na_2O_2` is a peroxide and contains a peroxy -O-O- linkage in which the oxidation state of oxygen is -1. Thus, for `Na_2O_2` , we have
`(2 xx x) + (-1 xx 2 ) = 0`
or `x = + 1`. S
