Soap solution, CuSO4 solution, Animal blood, sugar solution, salt solution,
Muddy water, Chalk & water mixture, Tooth paste, Milk, Starch solution,
Mist, Fog, Smoke..

Tell me right answers,wrong answers will be reported..​

Answer 1

Explanation:

Soap solution, CuSO4 solution, Animal blood, sugar solution, salt solution,

Muddy water, Chalk & water mixture, Tooth paste, Milk, Starch solution,

Mist, Fog, Smoke..

Let's classify them all in 3 categories - Colloids, Suspension, True solution.

• Colloids - Blood, Milk

• Suspension - Muddy water, Solution of copper sulphate

• True Solution - Sugar solution

Let's learn quite a more about them all,

• Colloids are hetrogeneous Mixture which seems to be homogeneous. Milk and blood shows no other layer, and seems to be homogeneous but it's composed of fats, calcium and RBC's etc etc respectively.

• Suspensions are hetrogeneous Mixture in which solute particles do not dissolve and remain suspended in the Mixture. A solution of muddy water is a perfect example, we can see soil particles moving in the solution.

• True solutions are homogeneous mixtures in which solute particles dissolve completely. Sugar solution is a perfect example, sugar particles dissolve completely in liquids and accquire space between the intermolecular particles of solids, and thus the solution exists in one phase.
