QUOTE(Najmods @ May 2 2010, 02:05 AM) Looks like someone don't pay attention in class. You need water, or at least water vapor, to ignite the alkali metal, you don't 'burn' it. If you asked me I would rather use Magnesium Group 1 metals more reactive than Group 2. Lithium and sodium will burn instantly when water vapour in the air react with them. That's why all lab group 1 metal are stored in parafin oil. However, magnesium metal only rust when in contact in air. That's why in lab you usually use magnesium ribbon and have to scrap off the black stuff.Or you just put it under your car tires and roll them over. Simple   End of chem class  |
