State symbols are symbols used in a symbol equation to identify the state of chemicals in a reaction.

The state symbols are:

Hydrogen + Oxygen → Water

H_{2 (g)} + O_{2 (g)} → H₂O_(l)

Magnesium + Oxygen → Magnesium Oxide

2Mg + O_{2 (g)} → 2MgO_(s)

Sodium Iodide + Lead Nitrate → Sodium Nitrate + Lead Iodide

2NaI_(aq) + Pb(NO₃)_{2 (aq)} → 2NaNO_{3 (aq)} + PbI_{2 (s)}

Sodium Hydroxide + Chlorine → Sodium Hypochlorate (Bleach) + Sodium Chloride + Water

2NaOH_(aq) + Cl_{2 (g)} → NaOCl_(aq) + NaCl_(aq) + H₂O_(l)
