  1. Greetings to everyone,

    We are doing the thumbnails practical this week,

    It takes some cocoa powder to be spread on the glass surface (e.g. microscope slide)

    Could we use alternatively chocolate powder? (e.g. Cadbury's)

  2. Aren't they the same thing?
  3. No. Cocoa powder consist only of ground cocoa beans after the fats have been removed. Drinking chocolates like Cadbury's have sugars and maybe creamer/milk powder as well. Don't know the practical so don't whether this is important.
