explain emulsion and all its types
Answers
Answer:
An emulsion is a colloid of two or more immiscible liquids where one liquid contains a dispersion of the other liquids. In other words, an emulsion is a special type of mixture made by combining two liquids that normally don't mix. The word emulsion comes from the Latin word meaning "to milk" (milk is one example of an emulsion of fat and water). The process of turning a liquid mixture into an emulsion is called emulsification.
Key Takeaways: Emulsions
- An emulsion is a type of colloid formed by combining two liquids that normally don't mix.
- In an emulsion, one liquid contains a dispersion of the other liquid.
- Common examples of emulsions include egg yolk, butter, and mayonnaise.
- The process of mixing liquids to form an emulsion is called emulsification.
- Even though the liquids that form them may be clear, emulsions appear cloudy or colored because light is scattered by the suspended particles in the mixture.
Properties of Emulsions
Emulsions usually appear cloudy or white because light is scattered off the phase interphases between the components in the mixture. If all of the light is scattered equally, the emulsion will appear white. Dilute emulsions may appear slightly blue because low wavelength light is scattered more. This is called the Tyndall effect. It's commonly seen in skim milk. If the particle size of the droplets is less than 100 nm (a microemulsion or nanoemulsion), it's possible for the mixture to be translucent

Answer:
An emulsion is mixture of two liquids that would not normally mix. That is to say, a mixture of two immiscible liquids. By definition, an emulsion contains tiny particles of one liquid suspended in another. Chemically, they are colloids where both phases are liquids.

Common examples of emulsions include egg yolk, butter, and mayonnaise. The process of mixing liquids to form an emulsion is called emulsification.
There are two basic types of emulsions: oil-in-water (O/W) and water-in-oil (W/O). These emulsions are exactly what they sound like, as pictured below. In every emulsion there is a continuous phase that suspends the droplets of the other element which is called the dispersed phase.
