explain the following given examples (a) saturated solution (b) pure substance (c) colloid (d) suspension
Answers
a)A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated.
b)In chemistry, a pure substance is a sample of matter with both definite and constant composition and distinct chemical properties. To avoid confusion, a pure substance is often referred to as a "chemical substance."...
c) In simple terms, we can define colloids as a mixture where one of the substances is split into very minute particles which are dispersed throughout a second substance. The minute particles are known as colloidal particles.
Answer:
A saturated solution is a solution that contains 1)the maximum amount of solute that is capable of being dissolved.
Examples: Adding sugar to water until it no longer dissolves creates a saturated solution.
2)In chemistry, a pure substance is a sample of matter with both definite and constant composition and distinct chemical properties. To avoid confusion, a pure substance is often referred to as a "chemical substance.
Examples: pure substances include hydrogen, water, silver .
3)a homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance.
Examples: milk, butter and muddy water
4)mixture of sand and water forms a suspension. A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution, so gravity is able to pull them down out of the dispersion medium
Examples:suspension include the mixture of chalk and water, the mixture of flour and water,
