Properties of Sulphur Video Lecture - NEET

sulfur is the 16th element of the
periodic table and is a nonmetal in its
elemental form it is a bright yellow
crystalline solid at room temperature in
this video we are going to look at the
basic physical and chemical properties
of sulfur we will also discover some
real-life applications of sulfur
containing compounds including how it is
found in fuels and what happens when it
is combusted and consequently reacts
with oxygen the most common eletric of
sulfur is Octus offer where 8 sulfur
atoms joined together to form this ring
structure and is very prevalent in
nature it is commonly found around
volcanoes yellow elemental sulfur burns
with a blue flame and melts into a deep
red liquid its many compounds can be
found in everyday life as cutting onions
reduce you to tears the sulfur
containing compound responsible for this
is a known substance that makes your
eyes produced years stinky feet in bad
breath blame those on sulfur containing
compounds to over cook those boiled eggs
that blue gray lining around the yolk is
due to the reaction of the iron the yolk
and hydrogen sulfide created in the
whites forming an iron sulfide never
smelled a natural gas leak that is
actually the smell of a spiking agent
which is a class of sulfur containing
compound called files or mercaptans such
as Mithun file methane is the gas the
file is the sulfur smell impart the
sulfur smell is strong enough so that
you can detect a potentially dangerous
leak in fact fuel for cars and other
vehicles also contain these sulfur
compounds the combustion of these fuels
also means the combustion of these
sulfur containing compounds this results
in the production of sulfur dioxide
which reacts with the oxygen in the air
to create sulfur trioxide sulfur
trioxide then reacts with water vapor in
the atmosphere to produce sulfuric acid
sulfuric acid then dissociates into its
respective ion
meaning there is a higher concentration
of hydrogen or rainwater and so the pH
is lower this means that it is acidic
bicycle and car tires would not exist
without sulfur white latex is tapped
from rubber trees in this national state
it's not very useful so it is vulcanized
or cooked with sulfur to make it harder
stronger and longer lasting in its
natural state the rubber molecules on
long chains that are tangled up and only
weakly linked when it is vulcanized
sulfur helps form extra bonds which are
known as cross links this makes it
harder did you know that curly hair has
a connection to sulfur carotene the main
protein component of hair also has lots
of disulfide bridges the more bridges
present the curvier your hair in fact
straightening curly hair involves
breaking these bridges either using heat
or chemicals do you love the smell of
the seaside that distinct smell is
actually from sulfur containing
compounds released by algae a
decomposing seaweed which is very toxic
but present in low enough concentrations
so that it is safe for you to enjoy your
time at the beach and finally and maybe
most importantly sulfur is an essential
element to life it is present in one of
the 22 amino acids that make up proteins
so when living things die and get buried
on the ground to form fossil fuels the
sulfur remains there only to be released
as ozone
when the fuels are burnt again leading
us back to acid rain so there you have
it
sulfur not as dull as you might have
imagined just remember volcanoes onions
smelly feet and eggs gas fuel as a brain
curly hair the seaside and amino acids
you
