What is a mixture where the substances do not settle over time?
A homogeneous mixture is a type of mixture where the substances are evenly distributed and do not settle over time. This results in a uniform appearance throughout the mixture. Examples include saltwater and air.
What is the difference between a solution a colloid and a suspension?
Colloids are particles smaller than those in a suspension. The basic difference between a colloid and a suspension is the diameter of the particles dispersed. Colloids are generally 1 to 5 nanometers while suspensions are usually 1000 nanometers. Colloids are usually harder to detect / see with the naked eye or microscope for this reason. Gelatin, butter, smoke, and fog are examples. A muddy delta is an example of a suspension.
What is the difference between colloids and suspension?
colloids are intermixing of two sol.
How are colloids solution and suspension different from each other?
Colloids have particles that are intermediate in size between solutions and suspensions and do not settle out over time like suspensions. In a solution, the solute particles are evenly distributed and do not settle out, whereas in a suspension, the solute particles are larger and settle out over time.
How can colloid's be distinguished from suspension?
Particles cannot be filtered from colloids. A colloid is distinguished from a solution and a suspension by the particles because they usually have an electric charge, and they repel each other, so they do not collect into larger particles that would settle out like those in solutions, and suspensions.
Are all mixtures soulutions?
No, not all mixtures are solutions. Solutions are homogeneous mixtures where one substance (solute) is uniformly dispersed in another substance (solvent). Other types of mixtures include suspensions and colloids, which are not considered solutions.
What are the different kinds of mixtures?
Mixtures are substances that are made by physical combination of one or more substances and none of the constituent elements are changed. The basic classification of mixtures is into homogeneous and heterogeneous substances. They can also be further divided under these two categories in to solutions, dispersions or colloids. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances. Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures. A homogeneous mixture in which there is both a solute and solvent present is also a solution. Heterogeneous mixtures include fine sand or silt in water.
Is all mixtures are solutions true or false?
False. As an example wet sand is a mixture of water and sand, but it is not a solution as the two substances remain as distinct phases.
What is solution and suspension?
(I may not be spot-on, I'm not quite a Science major.) A solution is a mixture of a liquid and one or more solids that have dissolved in the liquid and is inseparable. A suspension involves a solid and liquid; but the solids have not dissolved and are spread throughout the liquid or have settled at the bottom and have dissolved very little, or have not dissolved.
What is a mixture in which some of the particles will settle out?
Mixtures in which some of the particles settle out are called suspensions. An example of a mixture is dirt mixed with a large amount of water. On the other hand, mixtures in which the particles do not settle out are called colloids.
What kind of a mixture is toothpaste?
Toothpaste is a heterogeneous mixture, as it contains various components that are not uniformly distributed throughout the mixture. These components include abrasives, fluoride, flavorings, and other additives that give toothpaste its cleaning and protective properties.
What is one property of a suspension that is different from that of a sulotion or a colloid?
they are able to scatter light
