Question

What is suspension in chemistry

Answer 1

HEY FRIEND HERE IS YOUR ANSWER

Suspension is a heterogenous mixture with solute particles big enough to be seen from naked eyes. Some features of suspension are-

●They are heterogeneous

●solute particles are visible

●displays tyndall effect i.e a beam of light is visible in it if it passes through a suspension.

●It is unstable. The solute particles settle at the bottom if left undisturbed.

●Solute and solvent can be separated by the method of filtration.

●example-muddy water, sand water.

Answer 2

In chemistry, a suspension is aheterogeneous mixture that contains solidparticles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than 1 micrometer, and will eventually settle. A suspension is a heterogeneous mixture in which the soluteparticles do not dissolve, but get suspended throughout the bulk of the solvent, left floating around freely in the medium.[1] The internal phase (solid) is dispersed throughout the external phase (fluid) through mechanicalagitation, with the use of certain excipients or suspending agents. An example of a suspension would be sand in water. The suspended particles are visible under amicroscope and will settle over time if left undisturbed. This distinguishes a suspension from a colloid, in which the suspended particles are smaller and do not settle.[2]Colloids and suspensions are different fromsolution, in which the dissolved substance (solute) does not exist as a solid, and solvent and solute are homogeneously mixed.
