water is a
polar
compound
the
oxygen
atom binding with the
hydrogen
atom inside water molecule by
covalent
bond
the bond inside water compound is
covalent
bond
the bond between water compound moleceules
(between
H2O
and
H2O
) is called
hydrogen bond
unequality
in destribution of electrons leads to
polarity
covalent
bond in H2O is
polar
polar
:
unequality
in destibution of
electrons
non polar
:
equality
in destribution of
electrons
partial -ve
charge connect with
partial +ve
charge
water
moleceules are linked together by
hydrogen bond
water has a
high
boiling point
due to presence of hydrogen bonds
between water molecules, but more
heat
is needed to break down the
hydrogen bond
water is a
universal
(
common
)
solvent
water
has an ability to
dissolve
most of
substances
(
ionic
and
polar
substances)
water can dissolve
ionic
and
polar
substances but
can't dissolve
fatty acids
and
non polar
substances
cohesion
:
H2O
molecules
stick to other H2O molecules
by
hydrogen bond
so water molecules appear as one
column.
(
attatchment of water with water
)
Adhesion
:
H2O
molecule stick to a
non water
molecule
(
shape of container
)
surface tension
is the force that
keeps water droplets from touching the surface of a liquid
surface tension depends on
cohesion
and
adhesion
but
cohesion
in a
higher
proportion than
adhesion
surface tension
explains why
some insects can walk on water surface
capillary action
is the
force of water moving up a surface due to the pressure of the water
in
capillary action
adhesion
force is
higher
than
cohesion
force
