Separating mixtures
Fichas del conjunto (10)
- 1Sieving is defined as a method in which two or more components of different sizes are separated from a mixture on the basis of the difference in their sizes. Thus, it cannot separate two substances in a mixture which have the same size.
- 2Evaporation: It is the process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the gaseous state.
- 3Distillation: is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation.
- 4Decantation: the process of pouring away a liquid while leaving a solid (often a precipitate) behind.
- 5Crystallization: s a natural process which occurs as materials solidify from a liquid, or as they precipitate out of a liquid or gas. This can be caused by a physical change, such as a temperature change, or a chemical change such as acidity
- 6Filtration: is the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance, called a filter.
- 7Magnetism: Movement of an electrical charge (which is the basis of electric currents) generates a magnetic field in a material.
- 8Paper Chromatography: in analytical chemistry, technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper.
- 9Centrifuging: is the technique which involves the application of centrifugal force to separate particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed.
