Inspectorcritic Posted May 13, 2013 Share Posted May 13, 2013 Years ago to obtain a certain green wavelength a few grains of salt was placed on a lens then an eye dropper of some chemical and I'm hoping that it is household or close to it cuz I dont want to order it from a chemical supply company. The solvent broke down the salt into a green puddle then left to evaporate. I need to know what was the chemical he used I just gotta have that wavelength again. Or if not a method of doing the same by using a 9 volt battery with water and salt running a current through it to get the same green wavelength?

spirochete27 Posted September 12, 2013 Share Posted September 12, 2013 Are you looking for a solvent that will dissolve table salt? In the wikipedia article about sodium chloride there is a table listing its solubility in various solvents. Methanol and glycerin both look likle decent options. I'm not sure which one will give you a green color. Link to comment Share on other sites More sharing options...
