Question

what is the net ionic reaction of MgCl2 + SrCl2

&

what is the net ionic equation of (NH4)2SO4 + MgCl2?

Answer 1

1)   no reaction takes place between MgCl2 and SrCl2 . because both are chlorides

2) complete equation : (NH4)2SO4 + MgCl2 --------------------> MgSO4 + 2NH4Cl

net ionic equation :

2NH₄⁺(aq) + SO₄^2-(aq) + Mg²⁺(aq)+2Cl^-(aq)---------> Mg²⁺(aq) + SO₄^2-(aq) + 2NH₄⁺(aq) + 2Cl^-(aq)

no precipitate is formed in the reaction .because all are soluble compounds

Answer 2

The net ionic reaction of MgCl2 + SrCl2 can be determined by examining the ions present and identifying the spectator ions that do not participate in the reaction.

The balanced molecular equation for the reaction is:

MgCl2(aq) + SrCl2(aq) -> MgCl2(aq) + SrCl2(aq)

In this case, both Mg2+ and Cl- ions are common to both sides of the equation and do not participate in the reaction. They are called spectator ions. The net ionic equation is obtained by removing the spectator ions from the equation:

Net ionic equation: No reaction occurs.

Therefore, the net ionic reaction of MgCl2 + SrCl2 is no reaction.

Now let's consider the reaction between (NH4)2SO4 and MgCl2.

The balanced molecular equation for this reaction is:

(NH4)2SO4(aq) + MgCl2(aq) -> 2NH4Cl(aq) + MgSO4(aq)

To obtain the net ionic equation, we need to identify the ions that are present in the solution and participate in the reaction.

The dissociation of (NH4)2SO4 and MgCl2 in water yields the following ions:

(NH4)2SO4: 2NH4+ and SO4^2- MgCl2: Mg^2+ and 2Cl-

Based on the balanced equation, the net ionic equation can be written as:

2NH4+ + Mg^2+ + 2Cl- + SO4^2- -> 2NH4+ + 2Cl- + MgSO4(aq)

Simplifying this equation gives us the net ionic equation:

Mg^2+ + SO4^2- -> MgSO4(aq)

Therefore, the net ionic equation for the reaction between (NH4)2SO4 and MgCl2 is Mg^2+ + SO4^2- -> MgSO4(aq).
