What are the steps for obtaining soluble salt crystals from an acid-base reaction?


(this is a required practical)

Part 1 - Obtain a solution of the soluble salt that we want

  1. Place dilute acid in a beaker and gently heat it.
  2. Add the solid base bit by bit until it stops reacting, which means it's in excess.
  3. Isolate the salt solution by filtering out the excess solid base using filter paper and a funnel.


Part 2 - Isolate the soluble salt crystals from the solution 

  1. Heat the salt solution gently in a water bath until crystals start to form.
  2. Let the solution cool further, which will cause more crystals to precipitate.
  3. Filter out the soluble salt crystals using filter paper and a funnel.
