(b)
Interpretation:
The net ionic equation for the reaction of
Concept introduction:
A chemical reaction represents the different species reacting to form products. For an ionic equation, all the species in aqueous phase are represented as their respective ions. The net ionic equation involves all ions except the spectator ions in the equation. Spectator ions are the ions which are common at both sides of the chemical reaction and get cancelled out in the net ionic equation.
