Container of chlorine

Apearances
The containers of chlorine only appear in Fallout: New Vegas.

Location
Only two containers of chlorine exist in the game, one can be purchased from Ralph at Mick and Ralph's in Freeside, the other can be found in a storage room behind Mortimers desk in the Ultra-Luxe. However, you may also pickpocket the chlorine off of Ralph.

Uses
The only use of chlorine, is during the quest How Little We Know if you side with Nero and Big Sal by turning Cachino in. Big Sal asks you to see if or how you can help Clanden. If you pass a science check, he tells you that the Ultra-Luxe uses chlorine in their pools and that you can either find it there or try to find their supplier. The chlorine is needed to make a chlorine bomb which is evidently used during the fight for Hoover Dam.
