Net Ionic Equations

Part of the Acids and Bases section of Coddy's Chemistry journey. Lesson 19 of 30.

Ions that are the same before and after are spectator ions: Na⁺ and Cl⁻ in HCl + NaOH. Leave them out:

H₃O⁺ + OH⁻ → 2H₂O

A solid is written whole, since it is not split into ions:

Mg(OH)₂(s) + 2H₃O⁺ → Mg²⁺ + 4H₂O
