What is Ionic Equation?
A chemical equation that shows dissolved ionic compounds as separate ions rather than as neutral formula units. In a net ionic equation, spectator ions (ions unchanged in the reaction) are removed, showing only the species actually involved in the chemical change.

A chemical equation that shows dissolved ionic compounds as separate ions rather than as neutral formula units. In a net ionic equation, spectator ions (ions unchanged in the reaction) are removed, showing only the species actually involved in the chemical change.
Ionic equations are used in: predicting precipitation reactions (comparing ion products with Ksp), acid-base reactions (net ionic for strong acid + strong base: H⁺ + OH⁻ → H₂O), redox reactions, and complexation reactions. They clarify which species are chemically active and which are spectators, si…
Writing net ionic equations helps identify the reactive species, which may differ in hazard from the original reagents. For example, knowing that CN⁻ (not the sodium salt) is the toxic species in NaCN solutions helps direct appropriate antidote treatment (hydroxocobalamin, amyl nitrite for cyanide).
The formula or notation for Ionic Equation is: Ionic equation: show ions separately; Na⁺ + Cl⁻ + Ag⁺ + NO₃⁻ → AgCl↓ + Na⁺ + NO₃⁻
