Final answer:
The net ionic equation for the reaction between excess hydroiodic acid and sodium sulfite would involve the hydrogen ions reacting with sulfite ions to form sulfuric acid and water. However, the provided equations do not match the required chemical species for this specific reaction.
Step-by-step explanation:
The reaction between excess hydroiodic acid and sodium sulfite in aqueous solution can be represented by the net ionic equation that shows the species that actually change during the reaction. Hydroiodic acid is a strong acid and dissociates completely into hydrogen ions (H+) and iodide ions (I-). Sodium sulfite (Na2SO3) in aqueous solution dissociates into sodium ions (Na+) and sulfite ions (SO32-). The sulfite ions will react with the hydrogen ions to form sulfuric acid and water, a neutralization reaction.
The balanced net ionic equation for these species will not match any of the referenced equations since they involve different reactants and products.
