Concept explainers
(a)
Interpretation: To calculate the values of the degree of dissociation for formic acid and plot degree of dissociation against concentration. Also plot logarithm of concentration versus degree of dissociation.
Concept introduction: Degree of dissociation for formic acid is calculated from the relation of the degree of dissociation and concentration given below:
K=(Cο)(α2)(1-α)
A graph of degree of dissociation versus concentration of acid is plotted.
The logarithm of concentration versus degree of dissociation graph is plotted.
(b)
Interpretation:
Relationship of the degree of dissociation and initial concentration of an acid or a base has to be determined.
Concept introduction: Degree of dissociation for formic acid is calculated from the relation of the degree of dissociation and concentration given below:
K=(Cο)(α2)(1-α)
A graph of degree of dissociation versus concentration of acid is plotted.
The logarithm of concentration versus degree of dissociation graph is plotted.
