Write a net ionic equation for the reaction that occurs when excess hydrochloric acid (aq) and barium sulfite (s) are combined. Note: Sulfites follow the same solubility trends as sulfates.

Respuesta :

Balanced chemical reaction of hydrochloric acid and barium sulfite:

2HCl(aq) + BaSO₃(s) → BaCl₂(aq) + H₂O(l) + SO₂(g).

Balanced ionic reaction:

2H⁺(aq) + 2Cl⁻(aq) + BaSO₄(s) → Ba²⁺(aq) + 2Cl⁻(aq) + H₂O(l) + SO₂(g).

Net ionic reaction:

2H⁺(aq) + BaSO₄(s) → Ba²⁺(aq) + H₂O(l) + SO₂(g).

Answer: The net ionic equation is written below.

Explanation:

Net ionic equation of any reaction does not include any spectator ions.

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

The chemical equation for the reaction of hydrochloric acid and barium sulfite is given as:

[tex]2HCl(aq.)+BaSO_3(s)\rightarrow BaCl_2(aq)+H_2O(l)+SO_2(g)[/tex]

Ionic form of the above equation follows:

[tex]2H^+(aq.)+2Cl^-(aq.)+BaSO_3(s)\rightarrow Ba^{2+}(aq.)+2Cl^-(aq.)+H_2O(l)+SO_2(g)[/tex]

As, chloride ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

[tex]2H^+(aq.)+BaSO_3(s)\rightarrow Ba^{2+}(aq.)+H_2O(l)+SO_2(g)[/tex]

Hence, the net ionic equation is written above.
