This video shows how little material you require to show the beautiful precipitate of cobalt hydroxide using cobalt chloride and crushed pellet of sodium hydroxide. In fact, there that would have sup[lied enough sodium hydroxide for many more reactions. Now explain what is happening in terms of the particles, ie, the huge number of ions and water molecules, which are in random chaotic motion, yet for an “organised” precipitate line.
