Is sunscreen a solution or a mixture?
A uniform mixture where the particles (solid, liquid or gas) remain suspended (dispersed) among particles of the other (the medium) for a long period of time. They are useful for storing and delivering a substance to its target surface, eg, sunscreen.
Is hand lotion a colloid?
The particles in a colloid land in size between those in a solution and a suspension and may be solid, liquid or gas. Examples of colloids are foams (shaving cream, Styrofoam), gels (gelatin, jelly), emulsions (mayonnaise, lotion), aerosols (fog, insecticide spray, smoke) and sols (shampoo, gemstones).
What kind of mixture is a solution a suspension a colloid?
heterogeneous mixture
A solution is a homogeneous mixture of two or more substances, a suspension is a heterogeneous mixture containing particles that will settle out of solution, and a colloid is a heterogeneous mixture that contains particles that do not settle out of solution.
Is a snow globe a solution colloid or suspension?
A snow globe is a suspension mixture because when you shake it the snow is everywhere and over time it settles down.

Colloids are common in everyday life. Some examples include whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper. Every colloid consists of two parts: colloidal particles and the dispersing medium. Any colloid consisting of a solid dispersed in a gas is called a smoke.
What type of mixture is colloid?
A colloid is a heterogeneous mixture whose particle size is intermediate between those of a solution and a suspension. The dispersed particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas.
Is milk a colloid?
Milk is a colloid, with tiny globs of butterfat suspended throughout the liquid. Whipped cream is a colloid too. Colloids typically don’t separate into their individual components over time. suspension A mixture in which particles are dispersed throughout the bulk of a fluid.
Is a smoke a solution colloid or suspension?
Smoke is a colloid. Colloids are special solutions consisting of tiny particles that remain in suspension for a significant amount of time.
