Explain the following giving examples.
(a) saturated solution
(b) pure substance
(c) colloid
(d) suspension
Answers
a) Saturated Solution.
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.
for example :
Carbonated water is saturated with carbon, hence it gives off carbon through bubbles.
b) Pure Substance.
Pure substances are defined as substances that are made of only one type of atom or only one type of molecule (a group of atoms bonded together). The measure of whether a substance is pure is known as purity.
for example :
gold, copper, oxygen, chlorine, diamond, etc.
c) Colloid.
In chemistry, a colloid is a phase separated mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture.
For example :
the milk which contains a colloidal suspension of protein-rich casein micelles with a hydrophobic core.
d) Suspension.
A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase sometime after their introduction. We use the terms 'solute-like' and 'solvent-like' because we are dealing with a heterogeneous mixture, while the terms solute and solvent refer to homogeneous solutions.
for example :
Mud or muddy water: where soil, clay, or silt particles are suspended in water. Flour suspended in water.
