Question

When solid mg metal is put into an aqueous solution of snso4, solid sn metal and a solution of mgso4 result. write the net ionic equation for the reaction?

Answer 1

Mg(s) + SnSO₄(aq) = MgSO₄(aq) + Sn(s)

Mg + Sn²⁺ + SO₄²⁻ = Mg²⁺ + SO₄²⁻ + Sn

Mg + Sn²⁺ = Mg²⁺ + Sn

Answer 2

Answer: $Mg(s)+Sn^{2+}(aq)\rightarrow Mg^{2+}(aq)+Sn(s)$

Explanation:

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:-

$Mg(s)+SnSO_4(aq)\rightarrow MgSO_4(aq)+Sn(s)$

The complete ionic equation is:

$Mg(s)+Sn^{2+}(aq)+SO_4^{2-}(aq)\rightarrow Mg^{2+}(aq)+SO_4^{2-}(aq)+Sn(s)$

The $SO_4^{2-}$ ions which are present on both the sides of the equation are not involved in net ionic equation.

Hence, the net ionic equation is:

$Mg(s)+Sn^{2+}(aq)\rightarrow Mg^{2+}(aq)+Sn(s)$
