Question

Suspensions and collids short definition...

Answer 1

colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid;^[1] the term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the wordsuspension is distinguished from colloids by larger particle size). Unlike a solution, whosesolute and solvent constitute only one phase, a colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension). To qualify as a colloid, the mixture must be one that does notsettle or would take a very long time to settle appreciably

A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase sometime after their introduction. ... We apply the word 'suspension' when particles are big enough to eventually settle. If the particles are too small to ever settle, they are said to form a colloid
