STATE SYMBOLS OF REACTANTS AND PRODUCTS 12: State symbols of reactants and products: State symbols Sometimes it is useful to know whether the reactants and products in a chemical reaction are solids, gases, liquids or dissolved in water. We can add state symbol to a symbol equation to show this. State symbol and meaning Symbol Meaning (s) solid (l) liquid (g) gas (aq) aqueous (dissolved in water) m So for the reaction between sodium and water, this is the symbol equation co s. with state symbols: ce 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g) ur so --------------------------------------------------------------- re m Example 1: xa te [M/J/04-P3-3a] ar m.s w w w -------------------------------------------------------------- www.smartexamresources.com 1
