Key Stage 4
Meaning
State symbols are symbols used in a symbol equation to identify the state of chemicals in a reaction.
About State Symbols
The state symbols are:
Examples
Hydrogen + Oxygen → Water
H2 (g) + O2 (g) → H2O(l)
Magnesium + Oxygen → Magnesium Oxide
2Mg + O2 (g) → 2MgO(s)
Sodium Iodide + Lead Nitrate → Sodium Nitrate + Lead Iodide
2NaI(aq) + Pb(NO3)2 (aq) → 2NaNO3 (aq) + PbI2 (s)
Sodium Hydroxide + Chlorine → Sodium Hypochlorate (Bleach) + Sodium Chloride + Water
2NaOH(aq) + Cl2 (g) → NaOCl(aq) + NaCl(aq) + H2O(l)
