Question

In the reaction, 3Ni2 >2Ni* + Ni(s), the Ni2+ is a) oxidized, b) reduced, c) both, d) neither.

Answer 1

Answer: Option B , Reduced

Explanation:

Since oxidation number of Ni in Ni+2 is +2 and it is reduced to +1 and zero by gaining of Electrons.

2 moles of Ni+2 reduced from+2 to +1

state by gaining of 1 electron per each mole and another mole of Ni+2 reduced from +2 zero oxidation state by gaining of 2 electrons
