2. WHAT IS A SOLUTION
• A SOLUTION IS THE HOMOGENEOUS
MIXTURES OF TWO OR MORE
SUBSTANCES.
• EXAMPLES: LEMONADE , SODA WATER ,
AIR.
COMPONENTS OF SOLUTION
a. SOLUTE
b. SOLVENT
3. ABOUT SOLUTE AND SOLVENT
SOLVENT:
THE COMPONENT OF SOLUTION THAT
DISSOLVE THE OTHER COMPONENT IN IT IS
CALLED SOLVENT .
THE SOLVENT IS ALWAYS PRESENT IN MORE
QUANTITY.
SOLUTE:
THE COMPOENT OF SOLUTION THAT IS
DISSOLVED IN SOLVENT IS CALLED SOLUTE .
THE SOLUTE IS PRESENT IN LESSER QUANTITY.
4. EXAMPLES OF SOLUTIONS
SUGAR IN WATER.
SOLUTE- SUGAR
SOLVENT – WATER
---------------------------------------------------------------------------------------------
TINCTURE OF IODINE
SOLUTE: IODINE
SOLVENT : ALCOHOL
---------------------------------------------------------------------------------------------
AERATED DRINKS
SOLUTE: CARBON DIOXIDE GAS
SOLVENT: WATER
---------------------------------------------------------------------------------------------
AIR( MIXTURE OF GASES , TWO GASES WE ARE TAKING INTO
CONSIDERATION HERE ARE- NITROGEN & OXYGEN)
SOLUTE: OXYGEN (21%)
SOLVENT: Nitrogen (78%)
5. PROPERTIES OF SOLUTION
• A SOLUTION IS A HOMOGENEOUS
MIXTURE.
• THE PARTICLE SIZE OF SOLUTION IS LESS
THAN 1nm.
• DO NOT SCATTER A BEAM OF LIGHT.
• THE SOLUTE PARTICLES CAN NOT BE
SEPARATED FROM THE MIXTURE BY THE
PROCESS OF FILTRATION.
• SOLUTIONS ARE STABLE.
6. TYPES OF SOLUTION
• SATURATED SOLUTION
WHEN NO MORE SOLUTE CAN BE DISSOLVED IN
SOLUTION AT GIVEN TEMPERATURE , IT IS
CALLED AS SATURATED SOLUTION.
• UNSATURATED SOLUTION
IF THE AMOUNT OF SOLUTE CONTAINED IN A
SOLUTION IS LESS THAN SATURATION LEVEL
IT IS CALLED AS UNSATURATED SOLUTION.
7. METHODS OF EXPRESSING THE
CONCETRATION OF SOLUTION
• MASS BY MASS PERCENTAGE OF A SOLUTION
• MASS BY VOLUME PERCENTAGE OF A
SOLUTION
• VOLUME BY VOLUME PERCENTAGE OF
SOLUTION
