Iron (fe) reacts with copper sulfate (cuso4) to form iron (ii) sulfate. in this reaction, cu2+ gains electrons to form cu. which statement is true about this reaction?
fe(s) + cuso4(aq) → feso4(aq) + cu(s)

a.) cu undergoes decomposition.

b.) cu undergoes oxidation.

c.) cu undergoes reduction.

d.) cu undergoes combustion.

C.) Cu undergoes reduction.

Explanation:

I)  Oxidation reaction : involves loss of electrons and there is an increase in oxidation state number.

Fe metal has undergone oxidation, as its oxidation state is changing from 0 to +2 in .

ii) Reduction reaction : involves gain of electrons and there is a decrease in oxidation state number.

Copper(II) ion has undergone reduction, as its oxidation state is changing from 2+ to 0. Copper ions are getting converted into copper metal.
