MATTER
 Everything in the Universe is made up of MATTER

PURE SUBSTANCE
The substance which contains same kind of Atom or
Molecule

i] element
A pure substance which contain same kind of Atom

ii] compound
A pure substance which contain same kind of Atom or
Molecule but made up of different Atoms through a
Chemical bound

Mixture
Mixture are constitutor by more than one kind of

pure

form known as a substance




Substance

A substance cannot be separated into other kind of matter by any physical process
 EXAMPLE; sugar solution
 Salt solution
 Lemon solution
 HOMOGENEOUS MIXTURE

A mixture which has uniform composition in entire solution such mixture is called
HOMOGENOUS MIXTURE
A mixture which has a uniform composition in entire solution such mixtures are called
HOMOGENEOUS MIXTURE


In homogenous mixture absolve only single phase.
SOLUTIONS are also one kind of Homogeneous mixture
 SOLUTIONS
SOLUTIONS are divided into




SOLUTE+SOLVENT
EXAMPLE; if 100kg of solute +90G of
Solvent in water

 HETOGNEOUS MIXTURE
A mixture which contains no uniform solution in entire solution such mixtures are called HETROGENOUS MIXTURE
CONTAINS TWO PHASES

Example; salt + water

TRUE SOLUTION





Homogeneous mixture
Cannot be seen by naked eye
Cannot scatter a beam of light passing through the
Path of the solution
Cannot separate by normal filtration


COLLIDAL SOLUTION

Heterogeneous solution
 Cannot be seen by naked eye
 Scatter a beam of light on the path of solution this phenomena  Is called TYNDALL EFFECT
Cannot be speared by normal filtration by Centrifugation




SUSPENSION
Heterogeneous mixture
Can be seen with naked eye
Scatter a beam of light a make its path visible
Can be separated from normal filtration
