(a) Concentrated solution
Interpretation:
A concentrated solution contains a relatively large amount of solute.
Concept Introduction:
A solution is a heterogeneous mixture of two or more components. The solution is further divided into two components namely- solute and solvent. Solute is the minor constituent of the solution whereas the solvent is the major constituent. There is no visible layer of separation between the components of solution since the since the size of the solute particles is between 1-100nm.
E.g. sugar solution, the sugar added to water is solute and water is the solvent.
Some solutions have a high concentration of solute while some have low concentration. Since the amount of substance is comparable to the other hence, the solutions thus prepared are also comparable.
The relative terms used for them are concentrated and dilute.
A concentrated solution has more amount of solute dissolved in it as compared to the dilute solution.
(b) Dilute Solution
Interpretation:
A Dilute solution contains a relatively less amount of solute.
Concept Introduction:
There are two relative terms - dilute and concentrated. These two terms do not provide any quantitative information - but they are often useful in comparing the solutions. It just tells which solution has lesss amount of solute in comparison to the other.
(c) Soluble
Interpretation:
The term soluble implies a solute is fairly soluble in a solvent.
Concept Introduction:
Solubility is defined as the maximum amount of solute that can be dissolved in 100 g of solvent at a certain temperature to obtain a saturated solution. A saturated solution is a solution that has attained equilibrium and no further solute can be dissolved in the solution.
(d) Insoluble
Interpretation:
The term insoluble implies a solute is poorly soluble in a solvent.
Concept Introduction:
Solubility is defined as the maximum amount of solute that can be dissolved in 100 g of solvent at a certain temperature to obtain a saturated solution. A saturated solution is a solution that has attained equilibrium and no further solute can be dissolved in the solution.
If a solute does not dissolves completely in a particular solvent in any ratios, then the solute is said to be insoluble in that particular solvent.
