Question

Define the term solution. How many types of solutions are formed? Write briefly about each type with an example.

Answer 1

It is a homogeneous mixture of two or more than two components. There are three types of solutions:-

a. Gaseous solution:

A solutions in which solute may be liquid, solid, or gas but solvent is a gas, forms gaseous solutions. For example, a mixture of oxygen and nitrogen gas

b. Liquid solution:

A solution in which solute may be liquid, gas or solid but solvent is a liquid forms liquid solutions. For example, a solution of ethanol in water

c. Solid solution:

A solution in which solute may be liquid, gas or solid but solvent is a solid forms solid solutions. For example, a solution of copper in gold

Answer 2

Answer:

solution is a homogeneous mixtures of two or more than two substances on molecular level.The constitutent of the mixture present in a smaller amount is called the SOLUTE & the one present in larger amount is called the SOLVENT.For eg. Small amount of sugar(solute) dissolved in water(solvent).

SOLUTE + SOLVENT = SOLUTION

There are nine types of solutions formed.They are:

Sno

State of solute

State of solvent

Examples

1

GAS

GAS

Air

2

GAS

LIQUID

Oxygen in water

3

GAS

SOLID

Smole particles in air

4

LIQUID

GAS

Carbon dioxide dissolved in water

5

LIQUID

LIQUID

Alcohol in water

6

LIQUID

SOLID

Mercury in silver

7

GAS

Adsorption of hydrogen over palladium

8

LIQUID

Sugar in water

9

SOLID

SOLID

Carbon in Iron(steel)

Out of these nine types of solution , solid in liquid, liquid in liquid & gas in liquid are very common.When the components of the solution are mixed,the resulting solution may be in the solid, liquid or gaseous state.They are

(i) Gaseous solution:The solution in which the solvent is a gas is called a gaseous solution. In these solutions, the solute may be liquid, solid, or gas. For example, a mixture of oxygen and nitrogen gas is a gaseous solution.

(ii) Liquid solution:The solution in which the solvent is a liquid is known as a liquid solution. The solute in these solutions may be gas, liquid, or solid.

(iii) Solid solutions: The solution in which the solvent is a solid is known as a solid solution.The solute in these solutions may be a gas, liquid or solid. For example, a solution of copper in gold is a solid solution.
