Question

Explain
1 ) saturated solution,
2) pure substance,
3) colloid and
4) suspension

Answer 1

HEYA>>>>>

1.A solution that cannot dissolve anymore of the solvent at the given temperature.
2.A pure substance is a substance that has  definite proportions and specific chemical properties.
3.It is heterogenous solution which has particles of the size between  10^-7and 10^-5cm.
4.It is heterogenous solution which has particles of the size 10^-5cm and more


Hope it helps

Answer 2

Solution having higher concentration of solute than the solvent is called saturated solution
Substance having homogeneous composition of molecules of a single element. No other particles are present.
Colloids are the heterogeneous mixture having the particles size less than suspension and more than solution.
Suspension is the highly densed mixture having size particles more than solution and colloids.
