MgSO4 and Sr(NO3)2 are both soluble, so the ionic equation would look like this. Mg+2 + SO4-2 + Sr+2 + 2NO3-1 ---> Mg+2 + 2NO3-2 + SrSO4 SrSO4 is insoluble. Now Mg and 2NO3 are on both sides, so cross them out, the net ionic equation is SO4-2 + Sr+2 ----> SrSO4

The Net Ionic equation for the reaction between MgSO4 with Sr(NO3)2 is given by;  

Sr ⁺²(aq) + SO₄⁻²(aq) → SrSO₄(s)

Further Explanation

Net ionic equations

  • Net ionic equations that do not include all ions that are present in the reactants and products.
  • The equations only includes the ions that are involved in the reaction.
  • The ions that are not involved in a chemical reaction are called spectator ions and are cancelled out while writing ionic equations.
  • Reaction between MgSO4 with Sr(NO3)2 is an example of a displacement reaction.
  • During the reaction magnesium ion bonds with nitrate ions and forms magnesium nitrate, while strontium ion bonds with sulfate ion to form strontium sulfate.

That is:

MgSO₄(aq) + Sr(NO₃)₂(aq) → Mg(NO₃)₂(aq) + SrSO₄(s)

  • Mg ion remains in aqueous form in both magnesium nitrate and magnesium sulfate and therefore cancelled out since it is a spectator ion.
  • Additionally, Nitrate ion is also a spectator ion as it does not change state thus, also cancelled out while writing net ionic equation.

Therefore; the ionic equation required will be;

Sr ⁺²(aq) + SO₄⁻²(aq) → SrSO₄(s)
