Is Butter a Solution? Contrary to popular belief, butter is not a solution. Solutions are homogeneous mixtures in which the particles of the solute are completely dissolved in the solvent.

Is butter a suspension?
Colloids include fog and clouds (liquid particles in a gas), milk (solid particles in a liquid), and butter (solid particles in a solid). Other colloids are used industrially as catalysts. Unlike in a suspension, the particles in a colloid do not separate into two phases on standing.

A solution is a homogeneous mixture of two or more components. The dissolving agent is the solvent. The substance that is dissolved is the solute. The components of a solution are atoms, ions, or molecules, making them 10-9m or smaller in diameter. Example: Sugar and water
The particles in suspensionsare larger than those found in solutions. Components of a suspension can be evenly distributed by mechanical means, like by shaking the contents but the components will eventually settle out. Example: Oil and water
Particles intermediate in size between those found in solutions and suspensions can be mixed in such a way that they remain evenly distributed without settling out. These particles range in size from 10-8 to 10-6 m in size and are termed colloidal particles or colloids. The mixture they form is called a colloidal dispersion. A colloidal dispersion ...
Liquids, solids, and gasses all may be mixed to form colloidal dispersions. Aerosols: Solid or liquid particles in a gas Examples: Smoke is solid in a gas. Fog is a liquid in a gas. Sols: Solid particles in a liquid Example: Milk of Magnesia is a sol with solid magnesium hydroxide in water. Emulsions: Liquid particles in a liquid Example: Mayonnais...
You can tell suspensions from colloids and solutions because the components of suspensions will eventually separate. Colloids can be distinguished from solutions using the Tyndall effect. A beam of light passing through a true solution, such as air, is not visible. Light passing through a colloidal dispersion, such as smoky or foggy air, will be re...

Define emulsifying agent. Draw a picture of the molecular structure of an emulsifying agent and label the polar and nonpolar ends. Give 3 examples of common emulsifying agents.
Jun 10, 2019 · Butter and mayonnaise are examples of a class of colloids called emulsions. An emulsion is a colloidal dispersion of a liquid in either a liquid or a solid. A stable emulsion requires an emulsifying agent to be present.
Butter is an example of a colloid, specifically an emulsion. It is not a suspension or a solution. In butter, tiny droplets of water are dispersed throughout a matrix of fat.
Butter is a dairy product made by churning fresh or fermented cream to separate the butterfat from the buttermilk. Most frequently made from cows’ milk, butter can also be made from the milk of other mammals, including sheep, goats, buffalo, and yaks. Heavy cream is an emulsion.
