A few breaths at a concentration of 1000 ppm is usually fatal.
Oxidising
Very Toxic
Corrosive
Can ignite combustable substances
pools
marine pollutant

Question 3

Chlorine reactions

Answer 3

Oxidising
reactive with combustible subsatnces to cause fire
fumes in moist air
soluble in water and forms Hydrochloric acid
A mixture of Chlorine and Hydrogen explodes when exposed to sunlight to give Hydrogen Chloride. In the dark, no reaction occurs, so activation of the reaction by light energy is required.
Chlorine combines directly with most non-metals
Chlorine combines directly with all metals forming metal chloride salts.
