Tabulate the difference between a true solution ,collidal, and a suspension on the basis of
a. Particle size
b. Filterability
c. Stability
d. Homogeneity
Answers
Based on the nature of particle size, solutions are classified into THREE categories, namely (1) True Solution, (2) Colloidal Solution and (3) Suspension. Apart from the size differences of particles, these sub-categories of solutions also show considerable difference in their nature, colour, filterability and appearance.
(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.
