and so on.
In the presence of charcoal,chlorine and hydrogen combine rapidly,but without explosion,in the dark. A jet of hydrogen will burn in chlorine with a silvery flame and vice versa.
The affinity of chlorine for hydrogen is so great that chlorine will react with many compounds containing this element,for example hydrocarbons (a wax taper burns in chlorine).
Chlorine substitutes the hydrogen of methane giving successively the chlorides. It is to be noted that if a hydrocarbon is unsaturated,chlorine atoms will first add to the double or triple bond after which substitution may occur.
Chlorine will also remove hydrogen from hydrogen sulphide,liberating sulphur,and from ammonia,liberating nitrogen:
