FAQs on Separation Techniques - 1 Video Lecture - Chemistry for JAMB

1. What are separation techniques?
Ans. Separation techniques are methods used to separate mixtures into their individual components. These techniques are based on the differences in physical or chemical properties of the substances present in the mixture.
2. What are some common separation techniques?
Ans. Some common separation techniques include filtration, distillation, chromatography, evaporation, and centrifugation. These techniques are used to separate mixtures based on properties such as particle size, boiling point, solubility, or density.
3. How does filtration work as a separation technique?
Ans. Filtration is a separation technique used to separate solids from liquids or gases. It works by passing the mixture through a filter medium, such as a porous paper or a mesh, which allows the liquid or gas to pass through while retaining the solid particles.
4. What is distillation and how does it separate mixtures?
Ans. Distillation is a separation technique used to separate liquids based on their different boiling points. It works by heating the mixture to vaporize the substance with the lower boiling point, and then condensing the vapor to collect the separated liquid.
5. How does chromatography separate mixtures?
Ans. Chromatography is a separation technique that separates mixtures based on the differences in their distribution between a stationary phase and a mobile phase. The components of the mixture are carried over the stationary phase by the mobile phase, and their separation is achieved based on their different affinities for the stationary phase.
