Title: Diffrent kinds of salt from seawater
Post by: Scratch- on July 12, 2004, 12:51:56 PM
What kinds of salt can I extract from seawater? I know there is sodium chloride and an iodine salt but what others are there? I would like to set up an experiment where I separate the different kinds of salt, perhaps by crystallization, any ideas?

I would suspect its primary potassium, sodium and magnesium salts.

I once had an idea about obtaining iodine from seaweed, apparently the iodine can be liberated by burning dried seaweed to ashes, acidifying with H2SO4 and sublimation of I2.

This would be a good way to get iodine IMHO since it IS watched carefully by law enforcement..::EDITED::... ;D
