Method for the production of Sodium Carbonate solution

  1. Use the volumetric flask to get 250cm3 of distilled water
  2. Place 2.65g of sodium carbonate in a petri dish (weighed on the electronic balance).
  3. Pour the solid into a beaker. Wash the petri dish with some (perhaps 10cm3) of the 250cm3 distilled water so that all of the solid is used and place the washings in the beaker also. Then pour the rest of the distilled water.
  4. Stir with glass rod so that the ...
