Concept explainers
(a)
Interpretation:
Stronger acid among pyruvic acid and lactic acid to be identified.
Concept Introduction:
pKa is the negative of logarithm of dissociation constant of acid used to determine the acidity of an acid.
Higher the value of pKa, lower will the acidic character or lower the value of pKa, higher will the acidic character.
(b)
Interpretation:
Stronger acid among Phosphoric acid and citric acid to be identified.
Concept Introduction:
pKa is the negative of logarithm of dissociation constant of acid used to determine the acidity of an acid.
Higher the value of pKa, lower will the acidic character or lower the value of pKa, higher will the acidic character.
(c)
Interpretation:
Stronger acid among lactic acid and benzoic acid to be identified.
Concept Introduction:
pKa is the negative of logarithm of dissociation constant of acid used to determine the acidity of an acid.
Higher the value of pKa, lower will the acidic character or lower the value of pKa, higher will the acidic character.
(d)
Interpretation:
Stronger acid among carbonic acid and boric acid to be identified.
Concept Introduction:
pKa is the negative of logarithm of dissociation constant of acid used to determine the acidity of an acid.
Higher the value of pKa, lower will the acidic character or lower the value of pKa, higher will the acidic character.
