Q.1 Define a true solution?
Ans.
When
two or more than two substances mixed with each other resulting in a
homogeneous mixture forming a single phase, the solution is known as true
solution. The components of a true solution cannot is distinguished and never
settled down by the force of gravity. The components of a true solution can
only be separated using different analytical techniques such as evaporation and
distillation.
Q.2 What is meant by a binary solution?
Ans.
A
solution which possesses two components only is specifically known as a binary
solution. For example, a solution of salt into water is an example of binary
solution.
Q. 3 Enlist different concentration units of a solution?
Ans.
Divergent
concentration units are used for the quantitative study of a solution in which
amount of solute dissolved into solvent is estimated. Following are different units
to estimate the concentration of the given solution
I) Percentage
II)
Molarity
III)
Molality
IV)
Normality
V)
Mole fraction
VI)
Formality
Q. 4 What is a standard solution?
Ans.
A
solution of known concentration or strength is known as a standard solution.
Q. 5 Differentiate between concentration and amount of a substance?
Ans.
The
quantity of a given substance which is measured or weighed independently in its
original state is known as amount of that substance. However, when the given
amount of a substance is dissolved in a unit volume of a solution than this
amount is estimated in terms of concentration.
