Shaving cream is a colloid. Colloids are mixtures in which particles are dispersed throughout a medium (in this case, liquid) but are not dissolved. The particles in shaving cream are suspended in the liquid, giving it its characteristic creamy texture.
colloid
A Suspension is a mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas, a Colloid is a mixture in which the particles are dispersed throughout but are not heavy enough to settle out, and a solution is a uniform mixture that contains a solvent and at least one solute.
If a mixture settles over time and separates it is a suspension (milk with chocolate added). If a mixture does not separate overtime but forms lumpy or fluffy masses (like cottage cheese) it is a colloid. If a mixture does not separate or form lumpy masses it is a solution. Suspensions separate, colloids form lumps and may look 'cloud-like' and solutions remain the same.
The mixture of pepper and water is a suspension because of the particles. You see, a suspension is a mixture in which particles can be seen and easily separated by settling or filtration. Unlike a solution, a suspension does not have the same properties throughout. It contains visible particles that are larger than the particles in solutions or colloids.
A colloid is a mixture of solid particles suspended in a liquid.
Particles in solutions are evenly distributed and small enough to not settle out or be filtered out easily. In contrast, particles in suspension are larger and will settle out over time or with filtration. Solutions are typically clear, while suspensions may appear cloudy or opaque due to the presence of suspended particles.
the solid particles in these colloids are mixed with the particles of a liquid. the dispersed particles do not dissolve into the liquid therefore the particles do not settle.
Milk is a colloid, as it consists of fat globules suspended in a liquid solution. Colloids are mixtures where particles are evenly dispersed but not dissolved.
Suspension is a heterogeneous mixture in which insoluble solid particles are dispersed in a liquid. Colloids are homogeneous mixtures where particles are intermediate in size between those in a solution and a suspension, and do not settle out. Solutions are homogeneous mixtures where substances are completely dissolved in a solvent.
Colloids are particles of a certain size...around a micron to a fraction of a micron in diameter. The key characteristic is mass/size...they are insoluble but form a suspension when added to a solvent... That is to say they tend not to precipitate or form a deposit...they float... gravitational forces are balanced by the physical properties of the solvent... think of upthrust.
Colloids and suspensions are both heterogeneous mixtures where particles are dispersed within a medium. However, colloids have smaller particles that do not settle out over time due to Brownian motion, while suspensions have larger particles that settle out due to gravity. Both colloids and suspensions can scatter light, making their solutions appear cloudy or opaque.
solutions is a mixture that is dissolved and so is a colloid which is suspened in a liquid.
A colloid refers (it seems) chiefly to a liquid. As an aerosol is defined as a particulate (solid or liquid) suspended within a gas, this it isn't a relevant question with regards aerosol science. However colloids do exist within an aerosol spray, however once they are dispensed they become an aerosol.
The general classes of colloids are sols (solid particles dispersed in a liquid), gels (cross-linked networks of solid particles dispersed in a liquid), and emulsions (liquid droplets dispersed in another liquid).
Shaving cream is a colloid. Colloids are mixtures in which particles are dispersed throughout a medium (in this case, liquid) but are not dissolved. The particles in shaving cream are suspended in the liquid, giving it its characteristic creamy texture.
Conditioner is typically a colloid suspension, which means that it contains small particles suspended in a liquid. These particles help to smooth and moisturize the hair when the conditioner is applied. Some conditioners may also contain solutions, where the active ingredients are dissolved in the liquid instead of being suspended as particles.
