Question
The heterogeneous mixture, in which solute particles do not dissolve but remain suspended throughout the medium, is called?
Answer (Detailed Solution Below)
The correct answer is Suspension
A suspension is a heterogeneous mixture in which the solid particles are spread throughout the liquid without MIXING in it.
Properties of suspension:
- The size of solute particles in a suspension is somewhat large.
- The particles of a suspension can be seen easily by naked eye.
- The particles of a suspension do not pass through by filtration.
- The suspension is unstable. The particles of a suspension settle down at the bottom.
- A suspension scatters a beam of light passing through it because of its large particle size.
- Unsaturated solution: An unsaturated solution is a solution where the amount of solute dissolved is less than the saturation point of the solvent at a given temperature. In other words, the solution can dissolve more solute. For example: a glass of water with ice cubes, a cup of coffee with milk and sugar, etc.
- Colloid: The particles of a colloid are uniformly mixed throughout the solution. Due to the relatively smaller size of particles as compared to that of suspension, the mixture appears to be homogeneous.but actually a colloidal solution is a heterogeneous mixture. example : blood, paints, perfume, etc.
- Saturated solution: A solution which contains the maximum amount of solute dissolved in a given quantity of the solvent at the given temperature and which cannot dissolve any more solute at that temperature is called saturated solution. For example sugar in water.
