A mixture can be classified as a solutionsuspension or colloid based on?

Answer 1

Solution is mixture of 2 or more substances in equal proportion such as sugar or salt in water.But to differentiate colloid and suspension solution,there is big diff. that in colloidal solution,size of colloidal particle is in between 1 to 1000 nm and they show scattering of light(even though they r not visible with naked eye) and for suspension solution,suspended particles r in range of size of more than 1000 nm.These particles can be seen through naked eyes.

Answer 2

Good question, You use the variables that make it a solution suspension or colloid. Like a solution is a mixture of dissolved particles, a suspention is partly dissolved particles that are suspended in the mixture, and a colloid is somewhere in between. -Zane Chandler

Answer 3

Fundamentally, the distinction is based largely on the size of the solid particles in the mixture. For materials of relatively low molecular mass, if the "particles" are individual molecules and/or ions, and therefore are smaller than the wave length of visible light, so that the particles cannot be seen, the mixture is a solution. Another criterion of a solution is homogeneity and consistency of chemical composition among samples of various parts of the mixture, from samples of barely visible size up to volumes of many liters or more.

In a suspension, the particles are large enough to be visible individually, and in most instances, the particles will spontaneously separate from the liquid parts of the mixture, by precipitation or flotation, under the influence of Earth's gravity.* Unless the particles happen to be transparent to visible light, the intensity of a beam of light passing through a concentrated suspension is noticeably reduced because of absorption of light by the particles, and many suspensions are essentially opaque to visible light.

Colloids constitute an intermediate stage between solutions and suspensions. The individual particles usually have an average size within the wavelengths of the shortest and the longest wavelengths of visible light, so that light passing through a modest thickness of a colloid is likely to be scattered at least as much as absorbed. Since light of longer wavelengths is more easily scattered than light of shorter wavelengths, a beam of initially white light passing through a colloid will often acquire a noticeable color in the emerging light beam, but the total intensity of the transmitted light will usually be greater than that emerging from a suspension of about the same concentration of the same total solids. Colloids are often characterized by the presence of relatively stable and effective particle-stabilization layers around the dispersed particles, so that the rate of separation between particles and the remainder of the mixture is very slow. As a result, colloids of particles, such as solid gold, with high densities compared to the density of water can be stable against settling for many days and sometime even for many years.

*If the particles and the continuous phase of the suspension happen to have the same density, gravitationally driven separation of this sort will not occur.

Answer 4

Colloids are classified frequently as solutions because the particles have very small dimensions.

Answer 5

based on size of its largest particle

Answer 6

The size of its particles

Answer 7

A suspension is a mixture.
