When the solid or liquid is dispersed in a gas it is called aerosol. E.g., smoke, fog.
When both the dispersed phase and dispersing medium is liquid, it is called emulsion. E.g., milk, face cream.
By centrifugation, in a centrifuge machine the colloidal solution is kept in a test tube, rotated very fast and due to centrifugal force the colloidal...
The scattering of light by colloidal particles is known as Tyndall effect.
Water can dissolve large number of substances in it.
Saturated solution on heating becomes unsaturated and unsaturated solution on cooling becomes saturated.
If the amount of solute contained in a solution is less than the saturation level, it is called an unsaturated solution.
The maximum amount of solute dissolved in a solvent at given temperature is called saturated solution, where no more solute can dissolve further.
The amount of the solute present in the saturated solution at the given temperature is called its solubility.
Aqueous solutions have water as solvent and non-aqueous solutions do not have water as solvent.
The concentration of a solution is the amount of solute present in a given amount of solution or the amount of solute dissolved in a given mass or vol...
The amount of solute dissolving in a solvent decides whether the solution is dilute or concentrated.
Cold-drinks, carbon dioxide gas as solute is mixed with water as a solvent.
The homogeneous mixture of two or more metals or a metal and non-metal is called an alloy. E.g., steel is an alloy of iron and carbon.
A solution of iodine in alcohol is known as tincture of iodine. It has iodine (solid) as the solute and alcohol (liquid) as the solvent.
The component of the solution that is dissolved in the solvent is called solute.
The component of the solution that dissolves the other component in it is called the solvent.
(c) difference in the boiling point should be less than 25K
