Week 6: Electrochemistry and Alchemy

Halogen of the Week: Chlorine

Chlorine is found in abundance on Earth and is ubiquitous in our lives. It makes up the table salt we eat everyday and is used in common chemical disinfectants like bleach as well as used to clean our drinking water. Chlorine is able to form compounds with almost all elements. In nature, Chlorine ions are found mostly in naturally occurring salts found in the ground and the oceans making up about 1.9% of the mass of seawater. That's a lot of Chlorine! Although it is so common, Chlorine gas is toxic and has been used as a weapon in the past. Whether used for good or bad, Chlorine is a big part of life on our planet.

Alchemy - science, art, magic - or all three?

Alchemy is certainly a science and by the care and precision it has required to be discovered over the years, alchemy would also qualify as an art. In terms of magic, it is dependent on what magic means I suppose. Arthur C. Clarke said "Any sufficiently advanced technology is indistinguishable from magic." But maybe that means that it is magic. The discoveries made in herbal medicinals in the past and the current super atom discoveries being made I think could certainly all qualify as magic in some time or context, and perhaps time and context don't really matter and it is just simply magical.
