AtomicNumber 17
Element Chlorine
Symbol Cl
AtomicMass 35.4527
NameOrigins Greek, chloros = pale green
YearDiscovered 1774
DiscoveredCredits C. W. Scheele at Uppsala, Sweden.
Remarks Yellow-green, dense, sharp smelling gas, Cl2; produced on a large scale by electrolysis of sodium chloride. Used as bleaching agent and to make organochlorine solvents and polymers (PVC).
DiagnosticTests Chlorine salts (along with F, Br, and I) will give a blue color to flames when heated on a copper disk. Treatment of the salt with concentrated H2SO4 acid will effervesce with the evolution of a greenish, sharp smelling gas (Cl2). Chlorine sometimes found associated with bromine or iodine so a precipitate with AgNO3 solution is white (AgCl), cream (AgBr), or yellow (AgI) depending on which anion predominates. The precipitate is soluble in NH4OH
