Sublimation and Deposition

Sublimation is the direct transition of a solid into vapor on heating without passing through liquid state. This occurs when the vapor pressure of the solid exceeds atmospheric pressure at a certain temperature. The opposite of sublimation i.e the transition from vapor directly to solid, is called Deposition. The solid formed when the vapor cools … Read more

Solvent Extraction

Solvent extraction is a separation technique that is used to separate components of a mixture based on their solubility in different solvents. It is also referred to as liquid-liquid extraction. Here is how it works: the mixture is first dissolved in a solvent, and then another immiscible solvent is added. The desired compound selectively dissolves … Read more

Applications of Distillation

After learning about distillation in the previous section, you might be wondering about its practical applications. Well, distillation plays a critical role in many industrial processes, particularly those involving the purification of substances, concentration of solutions, and extraction of valuable components from complex mixtures. Here are some of the areas where distillation is applied in … Read more

Distillation

Key Takeaways: Distillation is a separation technique that’s commonly used to separate components of miscible solutions by exploiting differences in their boiling points. It involves heating a liquid mixture to its boiling point to vaporize the more volatile components and then cooling the vapor to condense it back into liquid form. The condensed liquid, known … Read more

How to Separate Copper Sulphate from Aqueous Copper Sulphate 

Copper sulphate, also known as cupric sulphate or copper (II) sulphate, is a chemical compound commonly used in chemistry experiments and in various industries. When dissolved in water, it forms a distinct blue solution. However, there are times when we need to extract pure copper sulfate from this solution, for example, in laboratory research, industrial … Read more

Crystallization

Crystallization is another separation technique that chemists use to separate solids or soluble substances from their solutions. Generally, crystallization is a process that occurs when a substance solidifies from a liquid or precipitates out of a liquid or a gas. It is this process that chemists leverage in crystallization as a separation technique. Many solids … Read more
