The <u>correct net ionic equation</u> for the chemical equation involving the reactants Ba(OH)2(aq) and H2SO4(aq) is Ba²⁺ (aq) + 2OH⁻ (aq) + 2H⁺(aq) + SO4²⁻ (aq) --> BaSO₄(s) + H₂O(l)
<h3>Further Explanation
</h3>
The chemical reaction between Ba(OH)2(aq) and H2SO4(aq) will be given by;
Ba(OH)₂(aq) + H₂SO4(aq) --> BaSO₄(aq) + 2H₂O(l)
<h3>Net ionic equations </h3>
- Net ionic equations that do not include all ions that are present in the reactants and products.
- The equations only includes the ions that are involved in the reaction.
- The ions that are not involved in a chemical reaction are called spectator ions and are cancelled out while writing ionic equations.
- Reaction between Ba(OH)2(aq) and H2SO4(aq is an example of a neutralization reaction or a double displacement reaction.
- During the reaction Barium ion bonds with sulfate ions and forms barium sulfate which is a solid, while hydrogen ion bonds with hydroxide ion to form water which is a liquid
That is:
Ba(OH)₂(aq) + H₂SO4(aq) --> BaSO₄(s) + 2H₂O(l)
- Barium ion changes from aqueous to solid state barium sulfate there it is an ion involved in the reaction.
- Additionally, all the other ions are also involved in the reaction since they have changed their initial state. The chemical reaction has no spectator ions.
Therefore; the ionic equation required will be;
Ba²⁺ (aq) + 2OH⁻ (aq) + 2H⁺(aq) + SO4²⁻ (aq) --> BaSO₄(s) + H₂O(l)

Answer:
Iron is being oxidized at the anode and water is acting as the electrolyte.
Explanation:
When iron is exposed to oxygen and water , the rusting of iron takes place.
<u>The reaction taking place at anode : Oxidation of iron.</u>

The reaction taking place at cathode : Reduction of oxygen in the air.
The overall reaction:

The rust that is hydrated iron(III) oxide can form iron(II) ions which can react further with oxygen.

Thus, from the above reactions ,
Iron is being oxidized at the anode and water is acting as the electrolyte.
