Question

types of solution class 9th explain​

Answer 1

Answer:

1. Different types of Solutions On the bases of water as Solvent:

Solutions can be classified into 2 types on the basis of whether the solution is water or not,

• Aqueous Solution:- The solution in which any state of homogeneous compound completely dissolves in water, in which water acts as a solvent. Examples of this kind of solution are sugar/ salt in water, carbon dioxide in water.

• Non- Aqueous Solution:- These solutions are basically opposite of the Aqueous solution, as the solvent available in it is not water, could be anything else like, petrol, benzene, ether, etc. Examples of this kind of solution include phenolphthalein in benzene, sulfur in carbon disulfide, etc.

2. Different types of Solutions On the bases of an amount of solute added:

Solutions can be classified into 3 types on the bases of an amount of solute present in the solution,

• Saturated Solutions: A solution is said to be saturated only if it reaches its limit to dissolve any more solute in the solvent at a definite temperature.

• Unsaturated Solutions: If the solution can still dissolve more solute in solvent then it is said to be unsaturated solutions.

• Supersaturated Solutions: The solution in which solute is present in an excess amount, and are dissolved in the solvent forcefully by raising the temperature, is called as the Supersaturated Solutions. These excess solute particles are later found in the form of crystals with the help of the crystallization process.
