Answers
Answer:
Solution:
True solution - Salt solution, copper sulphate solution, sugar and water solution, vinegar, air, brass.
Colloidal solution - Milk, Blood, Soap solution, starch solution, ink
Suspension - Milk of magnesia, chalk powder and water solution, flour in water, muddy water.
A true solution has extremely small particles which cannot reflect light, hence a true solution cannot exhibit ‘Tyndall
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.
