    • Base
      • A substance that reacts with an acid to neutralise it and produce a salt
    • Alkali
      • A base which is soluble in water
    • Making salts from insoluble substances
      1. Add the solid to the acid until the reaction stops
      2. Filter
      3. Heat the filtrate until the solution is saturated
      4. Leave in a dry place for the rest of the water to evaporate
