Question

Colloidal particles eventually separate from the solvent. Suggest an explanation

Answer 1

colloids are the mixtures of one or more substances thar disperded as relatively large solid particles or liquid droplets throughout the solid particles liquid or gas medium. the particles of a colloid remain dispersed and do not settle due to gravity and are electrically charged and these particles are very small also called emulsion and during enough time these particles under gravity either float to the top,if less dense than the solvent and sink to the bottom if it is more dense than solvent(suspending medium) and emulsion can be break through evaporation freeze/thaw, solvents,salts etc.
