Concept explainers
Interpretation:
Sodium bicarbonate, NaHCO3, is the sodium salt of carbonic acid (H2CO3), pKa = 6.37. Which of the substances shown in Problem 2-44 [Acetone (pKa =19.3), 2, 4-pentanedione (pKa =9.0), phenol (pKa =9.9), Acetic acid (pKa = 4.76)] will react significantly with sodium bicarbonate is to be stated.
Concept introduction:
An ion which is a weak base can deprotonate only when the substance reacting with it has a pKa value than that of its parent acid.
To determine:
Which of the substances shown in Problem 2-44 [Acetone (pKa =19.3), 2, 4-pentanedione (pKa =9.0), phenol (pKa =9.9), Acetic acid (pKa = 4.76] will react significantly with sodium bicarbonate. pKa of carbonic acid, = 6.37.
