+# Chemistry - Term 4 Summary
+
+## Precipitation reactions
+
+- water cannot dissociate ionic lattice structure (e.g. NaCl and other salts)
+- aqueous ions combine to form a new compound
+- occurs when concentration exceeds solubility (precipitate = insoluble solid)
+- all group 1 ions are soluble
+
+e.g. NaCl(aq) + AgNO3(aq) -> NaNO3(aq) + AgCl(s)
+
+
+
+## Acids and bases
+
+## pH scale
+
+## Redox reactions
+
+Electrochemical series - higher equations are more likely to occur
