Answer : When we mix the aqueous solutions of magnesium sulfate with chromium acetate we get the following reaction :-
[tex]MgSO _{4} + Cr (C _{2}H _{3}O _{2}) _{2} ----\ \textgreater \ CrSO _{4} + Mg(C _{2}H _{3}O _{2}) _{2} [/tex]
It is an example of a displacement reaction that takes place. According to the OWL solubility preparation rules all the reactants are soluble and hence the reaction occurs.
The net ionic equation of the reaction is :-
[tex]SO _{4} ^{-2} _{(aq.)} + Cr^{+2} _{(aq.)} ----\ \textgreater \ CrSO_{4}_{(s)} [/tex]
