Chlorine (Cl2)

DESCRIPTION (Chlorine):

Liquid Chlorine is a clear amber color. Gaseous Chlorine is colorless with a strong odor. It is shipped in steel cylinders under its own vapor pressure of about 85 psig @ 70° F. Common uses for Chlorine are water purification, bleaching and the manufacture of various chemicals.
