Principles Related to Practical Chemistry Cheatsheet & Quiz

Purity of Substance: Methods such as crystallization, distillation, and chromatography are used to purify substances.
Filtration: Separation of solids from liquids using filter paper.
Crystallization: Technique to purify solid compounds by formation of pure crystals.
Distillation: Separation of liquids based on different boiling points.
Evaporation: Removing solvent to obtain solute after solution formation.
Separation of Mixtures: Techniques include sublimation, magnetic separation, and chromatography.
Chromatography: Separation of components based on different affinities towards stationary and mobile phases.
Sublimation: Solid changes directly into gas, used to purify substances like ammonium chloride.
Practical Preparations: Methods for preparing substances like soaps, salts, and fertilizers.
Laboratory Techniques: Includes weighing, measuring, heating, and handling chemicals safely.

Technique	Purpose	Example
Filtration	Separate insoluble solid from liquid	Sand from water
Crystallization	Purify solid compound	Sodium chloride purification
Distillation	Separate liquids by boiling point	Alcohol and water separation
Chromatography	Separate mixtures based on affinity	Leaf pigment separation
Sublimation	Purify solids that sublime	Purification of iodine

Practice Laboratory Methods: Familiarize with common chemistry lab techniques and their purposes.

Understand Separation: Learn the principles behind each separation technique.

Safety First: Always follow safety protocols when handling chemicals and equipment.
