1. How are colloidal, solution and suspension different from of each other?
Answers
Colloidal solutions are the type of mixture, where the solute (tiny particles or colloids) is uniformly distributed in the solvent (liquid phase). The suspension is the mixture, where the solute does not get dissolved, rather get suspended in the liquid and float freely in the medium.
(1). True Solution: a mixture of two or more substances in which the solute is completely dissolve in the solvent. The size of particles in a true solution will be less than 1 nm in diameter.
(2). Colloidal Solution: a heterogenous mixture of two or more substances in which the substance is evenly suspended in the other. The size of particles in a colloidal solution will be larger than that of a true solution and smaller than suspension. The size range of particles in a colloidal solution will be 1 - 1000 nm in diameter.
(3). Suspension: The size of particles in a suspension will be greater than 1000 nm. Suspension is a heterogenous mixture of two or more substances.
