Question

A colloid formed between two liquids is known as a(n)

Answer 1

An emulsion is a colloid formed between two liquids, such as oil and water, where the colloidal particles are dispersed throughout another liquid and do not settle out upon standing.

Step-by-step explanation:

A colloid formed between two liquids is known as an emulsion. In an emulsion, the colloidal particles are liquid droplets that are dispersed throughout another liquid. These two liquids would not normally mix, like oil and water. An emulsion is a type of colloidal dispersion where the particles involved are of intermediate size, ranging between 2-500 nm, and they do not settle out upon standing. Familiar examples of emulsions include milk and mayonnaise.

Colloids, in general, are a heterogeneous mixture whose particle size is larger than a solution but smaller than in a suspension, which makes them unique. The dispersed particles in a colloid are large enough to scatter light, a phenomenon known as the Tyndall effect, which can make colloidal mixtures appear opaque or translucent.

Answer 2

A colloid formed between two liquids is known as an emulsion, a mixture where tiny clumps of molecules are dispersed throughout another liquid, resulting in an opaque appearance due to the scattering of light.

A colloid formed between two liquids is known as an emulsion. This type of colloid is a heterogeneous mixture where the particle size is between that of a solution and a suspension.

In an emulsion, tiny clumps of molecules are dispersed throughout another liquid, making the mixture opaque due to the scattering of light, a phenomenon known as the Tyndall effect.

Common examples of emulsions include milk and cream, where fat droplets are dispersed in water. Emulsions are stabilized by emulsifying agents that combine a hydrophobic tail with a hydrophilic head, preventing the two insoluble liquids from separating.

A colloid like this does not settle out upon standing and remains evenly distributed throughout the liquid medium.
