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

Another separation technique that we can use to separate mixtures is the use of a separating funnel. In particular, a separating funnel can be used to separate a mixture containing two or more immiscible liquids. Immiscible liquids don’t mix. Instead, they form layers with the denser liquid sitting at the bottom of the funnel and … Read more

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 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

As a chemist, you have numerous methods at your disposal to separate sand and salt. However, the simplest approach involves combining two basic separation techniques we’ve previously discussed: filtration and evaporation. Through filtration, you can isolate the sand from the saltwater solution. And by subjecting the saltwater solution to evaporation, you’ll recover the salt in … Read more

Evaporation is the process through which liquid changes into vapor when heated. (The term vapor denotes a gas that can be condensed easily to liquid). It is one of the basic separation techniques in chemistry, which is majorly used to separate soluble solids from their solvents. For example, sodium chloride (common salt) readily dissolves in … Read more

Decantation Sand is insoluble in water. When you allow a mixture of sand and water to stand, the sand will start to settle at the bottom of the container. After all the sand has settled, you can carefully pour water out into another container with the help of a glass rod, leaving the settled solid … Read more
