TOPIC- SOLUTIONS, SUSPENSIONS AND COLLOIDS BY- ASHISH SHARMA SUBHAM NANDI SUBHAJIT PAIK A. LAKSHIT

SOLUTE AND SOLVENT:

SOLUTE AND SOLVENT THE SUBSTANCE WHICH IS DISSOLVED IN A LIQUID IS CALLED “SOLUTE”. THE LIQUID IN WHICH SOLUTE IS DISSOLVED IS KNOWN AS “SOLVENT”. EXAMPLE:- SALT SOLUTION IS MADE BY DISSOLVING SALT IN WATER, SO IN SALT SOLUTION ‘SALT’ IS THE SOLUTE, AND ‘WATER’ IS SOLVENT.

SOLUTION:

SOLUTION A solution is a homogeneous mixture of two (or more substances). Examples: salt solution, sugar solution, vinegar, metal alloys(such as brass)and air. Only soluble substances form true solution.

PROPERTIES OF SOLUTION:

PROPERTIES OF SOLUTION A solution is a homogeneous mixture. The size of a solute particle in a solution extremely small. It is less than 1 nm in diameter (1 nanometer=10 -9 metre). The particles of a solution cannot be seen even with a microscope. The particles of a solution pass through the filter paper. So, a solution cannot separated by a filtration. The solutions are very stable. The particles of solute present in a solution do not separate out on keeping. A true solution does not scatter light.

EXAMPLE:- SALT SOLUTION

TYPES OF SOLUTION:

TYPES OF SOLUTION Solution of solid to solid. Metal alloys are the solution in solids. Solution of solid in liquid. This the most common type solutions. Solution of liquid to liquid. Vinegar is a solution of acetic acid in water. Solution of gas in a liquid. Soda water is a s olution of co 2 in water. Solution of gas in a gas. Air is a solution of gases.

SUSPENSION:

SUSPENSION A Suspension is a heterogeneous mixture in which the small particles of a solid are spread throughout the liquid without dissolving in it. Examples: chalk-water, muddy water, milk of magnesia, sand particles suspended in water, flour in water. Those substances which are insoluble in water forms suspension.

PROPERTIES OF SUSPENSION:

PROPERTIES OF SUSPENSION A suspension is a heterogeneous mixture. The size of a solute particle in a suspension quite large. The particles of a suspension can be seen easily. The particles of a suspension do not pass through the filter paper. So, a suspension can separated by filtration. The suspension unstable. The particles of solute present in a suspension settle down after some time. A suspension scatters a beam of light passing through it.

EXAMPLE:- SAND-WATER MIXTURE

COLLOIDS:

COLLOIDS A colloid is a kind of solution in which the solute particles is intermediate between those a true solution and those in suspension. Examples: soap solution, starch solution, milk ink, blood, jelly and solutions of synthetic detergents. Colloids are also know as Colloidal solution.

PROPERTIES OF COLLOIDS:

PROPERTIES OF COLLOIDS A colloid is a heterogeneous mixture. The size of particles of a colloid is too small to be individually seen by naked eyes. Collides are big enough to scatter a beam of light passing through it and make its path visible. They do not settle down when left undisturbed , that is, a colloid is quite stable.
