y sand paper...?When using a magnesium ribbon or any dirty surface, clean it with SANDPAPER
When you have to remove moisture from :
1. Surface:
Wash the surface with a stream of propanone. The water gets dissolved in the propanone and repeat it multiple times. Then gently heat the surface to evaporate the propanone from the surface
2. Vapour:
Use dessicants such as:
1. ANHYDROUS sulphuric acid
2. ANHYDROUS calcium chloride
3. Silica gel
You have to pass the vapour from the beaker containing the dessicant
Also, a useful property of soda lime is that it absorbs BOTH water vapour and carbon dioxide
i dont know? lol u tell me...iam just goin through the points right now...and u do the same thing..ok anglegirl where do u want me to start from??
