Crystallization

Crystallization

is the process through which the atoms/molecules of a substance arrange themselves in a well-defined three-dimensional lattice and consequently, It is a practical method of obtaining pure chemical Substances in a satisfactory condition. When a substance is subjected to crystallization, its atoms or molecules bind together through well-defined angles

is an important step in the purification of materials. Improved crystallization processes can provide routes to higher-purity final products.

Filtration process is completed

the sand Separate in the filter paper and Salt with water moves down into the conical flask, proceed to Crystallization

Step 1

Take 30 ml water in a beaker

Step 2

Add 20g of salt in it and stir it

Step 3

Heat the solution (The solution is heated in an open container)

Step 4

Repeat the process continuously. The solvent molecules start evaporating, leaving behind the solutes.

Step 5

After some time, there will be a point at which no more salt can be dissolved in water. This stage is the saturation point

Step 6

When the solution cools, crystals of solute start accumulating on the surface of the solution.

Step 7

Filter the salt with the help of a filter paper

Unsaturated

Dissolved solute is below saturated point; more can dissolve

Saturated

Dissolved solute is at saturation point; no more can dissolve

Supersaturated

Dissolved solute is above saturated point; additional solute gathers at the bottom

Homogeneous mIxture

It has solution, uniform and its not visible

Hetergeneous mixture

It has no solution, non uniform and its visible

Filtration

The undissolved solids in the liquid are separated by the process of
