Question

The diameter of the solute particles in true solution
(a) 10^-5 – 10^–7 cm (b) < 10^–7 cm
(c) < 10^–4 cm (d) 10^–6 - 10^–8 cm

Answer 1

Answer:

Correct option is

A

Less than 0.001μm

Three types of solutions (true solution, suspension and colloids) are distinguished on the basis of particle size. By definition, a true solution is a homogeneous mixture of two or more substances in which substance dissolved (solute) in solvent has the particle size of less than 1 nm or 0.001 micrometers.

Hence the correct option is A.
