Question

Consider the reaction when aqueous solutions of magnesium sulfate and chromium(iii) acetate are combined. (use the solubility rules provided in the owl preparation page to determine the solubility of compounds.) the net ionic equation for this reaction is:

Answer 1

Answer : When we mix the aqueous solutions of magnesium sulfate with chromium acetate we get the following reaction  :-

$MgSO _{4} + Cr (C _{2}H _{3}O _{2}) _{2} ----\ \textgreater \ CrSO _{4} + Mg(C _{2}H _{3}O _{2}) _{2}$

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 :-

$SO _{4} ^{-2} _{(aq.)} + Cr^{+2} _{(aq.)} ----\ \textgreater \ CrSO_{4}_{(s)}$
