Question

(a) Write the balanced molecular and (b) net ionic equation for the redox reaction between Magnesium solid and cobalt(II) sulfate (c) identify what element is oxidized and what element is reduced. (please type the answer for part conly in the solution box. Oxidized Reduced

Answer 1

a) Balanced molecular equation :

Mg(s) + CoSO4(aq) -> Co(s) + MgSO4(aq)

b) Net ionic equation :

Mg(s) + Co^2+(aq) -> Mg^2+(aq) + Co(s)

c) Oxidized : Magnesium (Mg)

Because it's oxidation number increases from 0 to +2.

Reduced : Cobalt (Co2+)

Because it's oxidation number decreases from +2 to 0.
