Benefits of Separating Mixtures

 

Methods Of Separating Mixtures and It's Benefits

There are several ways of separating mixture .You can choose the most appropriate method of separation base on the properties of the substances involved. Some of the common methods of separating substances or mixtures are: 

• Physical Manipulation
• Sedimentation and Decantation 
• Hand Picking
• Sieving
• Evaporation
• Distillation
• Filtration or Sedimentation
• Separating Funnel
• Magnetic Separation

I will be discussing three of them in detail below.

1. Distillation

Distillation is used when mixtures consist of two or more pure liquids. The components of a liquid mixture are vaporized, condensed and then isolated. The mixture is heated and the component which is volatile evaporates first. The vapour moves through a condenser and is collected in a liquid state.

Benefits of Distillation Process

• Distillation is most effective in removing inorganic compounds such as metals (iron and lead) and nitrate; hardness (calcium and magnesium); and particulates from a contaminated water supply. The boiling process also kills microorganisms such as bacteria and some viruses.
• Distillation is the only process that collects the pure steam! The steam rises from the water, leaving virtually all other contaminants behind, then we cool the steam down into pure water!
• Distillation produces extremely consistent results! There is no drop in quality over time. Produces consistently high quality water glass after glass, day after day, and year after year.

2. Evaporation

Evaporation is a technique that is used in separating a mixture, usually a solution of a solvent and a soluble solid. In this method, the solution is heated until the organic solvent evaporates where it turns into a gas and mostly leaves behind the solid residue.

Benefits of Evaporation

Our clothes can become dry again after washing them. Because of vaporation, wet surfaces can become dry after being exposed in sunlight. Evaporation enables precipitation. Because of evaporation we have a rich hydrosphere.

3. Magnetic Separation

When one substance in the mixture has some magnetic properties then this method is quite useful. Strong magnets are commonly used to separate magnetic elements.

 

Benefits of Magnetic Separation

Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people's bodies.

I hope you find this topic helpful. Until my next blog.
