Question

What is the difference between homogenous mixture and a true solution? please give correct answer..I have science exam tomorrow​

Answer 1

Explanation:

True Solution :-

» It is a homogeneous mixture.

» The particles of true Solution are smaller than 1 nm (10^{-9} m10

−9

m )

» Due to their small size, the particles are not visible to naked eyes.

» The particles are equally distributed in true Solution.

» True Solution is stable, that is, the particles of true Solution do not settle down if left undisturbed.

» True Solution do not show Tyndall effect.

Example :- Salt in water.

→ Suspension :-

» It is a heterogeneous mixture.

» The particles of Suspension are larger than 10^{-7} m10

−7

m

» Due to their large size, the particles are visible to naked eyes.

» The particles are not equally distributed in suspension.

» Suspension are unstable, that is, the particles get settle down if left undisturbed.

» After settling down, they don't show Tyndall effect.

Example :- sand in water.

→ Colloidal Solution :-

» They seem to be homogenous but are heterogeneous.

» Particle size ranges between 10^{-9} to 10^{-7}10

−9

to10

−7

» They are small enough to not to be visible to naked eyes.

» The particles are equally distributed.

» The particles don't get settle down if left undisturbed.

» They show Tyndall effect.

Example :- Milk.

Answer 2

Answer:

homogeneous mixture is a mixture in which the composition is uniform throughout the mixture while true solution is a homogeneous mixture of two or more substances
