This document discusses solutions and factors that affect solubility. It defines a solution as a homogeneous mixture of two or more substances, with the substance that dissolves being the solute and the substance doing the dissolving being the solvent. It lists different types of solutions such as saturated, unsaturated, dilute, and concentrated. It also discusses that solubility is a measure of how easily a solute dissolves in a solvent. Finally, it outlines several factors that can impact solubility, including like dissolving like, temperature, molecular size, and stirring.

3. Solution and solubility

4. Solution is the homogenous mixture of two or more than
two things .
It consists of solute and solvent
Solute is that part which being dissolved
Solvent is the part which dissolve the solute
If the solute dissolves in solvent ,solute is known as the
soluble .
If solute can not be dissolved in solvent , it means solute is
insoluble in it.
Solution

7. Solutions are of following
types
Saturated solution: when no
more solute is dissolved in the solvent.
Unsaturated solution:when a
solvent dissolves more solute in it at a
particular temperature.

9. Kinds of solution
 Dilute solution :which contains small
amount of solute .
 Concentrated solution : which contains
large amount of solute.
 Aqueous solution: in which solvent is
water.

11. Do we get back
the solute and
solvent separate
from the
solution?

13. {
It is measure of how easily a solute
dissolves in the solvent
Or
it can be define as the quantity of solute
in grams dissolves in 100 grams of water
at a given temperature .
solubility

14. Factors effecting solubility
Like dissolves like
Polar substances tend to
dissolves in polar solvents
While non polar tend to
dissolve in non polar solvents

15. Temperature
Generally the solubility of solid
solutes increases with
increasement in temperature . Opposite of it is true for gases
High temperature drives gases out
of the solution
As the carbonated soft drinks are
more bubbly if stored in the
refrigerators.

16. Molecular size
The larger the molecules the larger their weight and size
So, it is more difficult for solvent to surround the larger molecules
So result is that the larger molecules are less soluble

17. Stirring effect
Stirring only increases
the speed of process .
It increases the movement
of solvent which expose
to the solute
thus enabling the
solubility
