Question

What is the net ionic equation of the reaction of mgso4 with ba(no3)2? express you answer as a chemical equation including phases. view available hint(s)?

Answer 1

The Molecular Equation is as follow,
 
         Ba(NO₃)₂ ₍aq₎  +  MgSO₄ ₍aq₎  →  BaSO₄ ₍s₎  +  Mg(NO₃)₂ ₍aq₎

The Total Ionic Equation is as follow,

Ba²⁺₍aq₎ + 2NO₃⁻ ₍aq₎ +Mg²⁺ ₍aq₎ + SO₄²⁻ ₍aq₎  →  Mg²⁺ ₍aq₎ + 2NO₃⁻ ₍aq₎ + BaSO₄ ₍aq₎

Here, Mg²⁺ and NO₃⁻ are spectator Ions,
So,
The Net Ionic Equation is as follow,

                            Ba²⁺ ₍aq₎  +  SO₄²⁻ ₍aq₎  →  BaSO₄ ₍aq₎

Answer 2

A double displacement reaction occurs between Barium Nitrate and Magnesium Sulfate, as shown below:          Ba(NO₃)₂ ₍aq₎  +  MgSO₄ ₍aq₎  →  BaSO₄ ₍s₎  +  Mg(NO₃)₂ ₍aq₎
Only the Barium ion (Ba²⁺) and the sulfate ion (SO₄²⁻) actually changed in terms of ionization as the rest of the ions are spectator ions.
