An Introduction to Chlorine

An Introduction to Chlorine
Chloros Greek for green!
Thats right! Its a greeney-yellow gas in its
natural state but its highly reactive.
Hasta La Vista Baby

The Formation of Chlorine
Chlorine can be obtained by electrolysis of
sodium chloride (brine the salty stuff canned
tuna is preserved in!)
3
Salt can also be obtained from salt mines
Rock salt
4
At the negative electrode, it was sheer magnetism
that brought the two hydrogen atoms and two
chlorine electrons together
5
And on the positive side, although the chloride
ions lost their electrons, they are oxidised by
this electron loss and become better molecules
(forming chlorine gas)
Youre far more reactive this way!

Properties of Chlorine
7 outer electrons group 7
Reacts well with heat and moisture
Element number 17
Goes around in 2s
7
Reactivity
Chlorine is never found as a free element in
nature
Sharon told me not to put chlorine on the fire
with organic material or it woulduh
Explode?!
8
Where else is Chlorine found?
Fungal activity
Forest fires
These compounds are known as natural
Organochlorines
In seawater
9
And by far the most bizarre
Yes its truethese little Ecuadorian tree frogs
actually make chlorine!
Morphine?! This frog produces a chlorinated
alkaloid whos pain killing properties are
several hundred times more powerful!
10
Although we eat chlorine as a compound every day
as salt, in its natural gaseous state its
extremely toxic and was used in WW1 to gas the
enemy

• Affects the nose
• Affects the eyes
• Gives breathing difficulties and finally
• Death by suffocation

Even Arnie wouldnt be able to withstand large
quantities of chlorine gas!
