Question

What is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants?

Answer 1

Answer : The correct net ionic equation is:

$Ba^{2+}(aq)+2OH^-(aq)+2H^+(aq)+SO_4^{2-}(aq)\rightarrow 2H_2O(l)+BaSO_4(s)$

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced molecular equation will be,

$Ba(OH)_2(aq)+H_2SO_4(aq)\rightarrow 2H_2O(l)+BaSO_4(s)$

The complete ionic equation in separated aqueous solution will be,

$Ba^{2+}(aq)+2OH^-(aq)+2H^+(aq)+SO_4^{2-}(aq)\rightarrow 2H_2O(l)+BaSO_4(s)$

In this equation, spectator ions are not present.

The correct net ionic equation is:

$Ba^{2+}(aq)+2OH^-(aq)+2H^+(aq)+SO_4^{2-}(aq)\rightarrow 2H_2O(l)+BaSO_4(s)$
