Solution

Mixtures are classified into True solution, colloid, and suspension depending upon the properties
True solution Colloids Suspension
The solute particles which are dissolved in the solvent has size less than 1 nm Collidal particles have sizes in 1-1000 nm size The suspended particles have greater than 1000 nm size, which we can easily see with the naked eye
Particles do not settle down, and do not show the Tyndall effect Particles do not settle down when left undisturbed, and show the Tyndall effect Particles settle down when left undisturbed
Example: sugar solution Example: milk Example: sand in water
By analyzing the properties of the solution, colloid, and suspension
Chalk powder and water is a suspension
The chalk powder doesn't dissolve in water
When the mixture is left undisturbed, chalk particles will settle down
It is a heterogeneous mixture where the chalk powder can easily be seen with the naked eye from the solution
We can easily filter the chalk particles using filter paper
Thus, we can say that chalk powder and water is a suspension
