Question

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

Assume that the contribution of protons from H₂SO₄ is near 100 %.

`Ba(OH)_2 (aq) + H_2SO_4 (aq) \longrightarrow`
Express your answer as a chemical equation.

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)`
