acids and bases - Coggle Diagram

- - - - acid + metal --> salt + hydrogen
    - - acid + base --> salt +water
    - - acid + metal carbonate + salt + carbon dioxide + water
    - - acid + ammonium --> ammonium salt + water
  - - - farmers typically use calcium oxide (an alkali/base) to neutralise soil
- - - - base + ammonium salt --> water + ammonia + salt
      - decomposition + needs heat
- - - - add solutions that will form the salt and stir, precipitation will occur
      - filter precipitation
      - wash the salt with distilled water
      - dry in an oven
  - - - heat acid and add metal/carbonate/base and stir
      - filter mixture with a funnel + filter paper to remove excess alkali
      - transfer filtered solution to an evaporating basin and heat it and allow solution to evaporate until a solid (crystals) appear
      - allow crystals to dry (crystalisation)
    - - add alkali and indicator to a conical flask
      - add acid into burette and write the starting point
      - perform a titration -> stop adding acid when indicator changes colour
      - calculate volume of acid added
      - add the same volume acid to the alkali
      - transfer solution to an evaporating basin and heat up until all water is removed and let it dry so salt can crystallise
