    It can be filtered, washed and dried in an oven
  • Is a base insoluble in water?
    Yes
  • What is the process in using a base to create a salt?
    1. Base is added until no more will dissolve
    2. Remove excess to obtain pure solution through filter paper
    3. Water is evaporated to get pure salt crystals
