Question

arrange the following in decrease order of size of the particles . True solution .suspension .colloid

Answer 1

Suspension > Colloid > Solution
> 100 nm >. 100nm - 1nm > 1nm

Answer 2

Decreasing order of size of the particles- suspension > colloid > true solution.

• A true solution is made of solute and solvent which are homogenous in nature. The solution is clearly transparent.
• Solute particles size of a true solution is less than 1nm i.e. very small in size.
• Due to its very small size, true solution particles are invisible.
• A colloidal solution is a heterogeneous mixture of solute and solvent but it seems to be homogenous and translucent
• Its particle size varies between 1nm to 100nm.

• With the help of a microscope, these particles can be seen.

• A suspension is a heterogeneous mixture of solute and solvent.
• The particle size of suspension is more than 100nm which is the largest among the true solution and colloids.
• These can be seen by the naked eye, due to their large size and their solution is opaque.
