Concept explainers
Interpretation:
It should be explained that the ascorbic acid
Concept introduction:
Acid - ionization constant
Acids ionize in water. Strong acids ionize completely whereas weak acids ionize to some limited extent.
The degree to which a weak acid ionizes depends on the concentration of the acid and the equilibrium constant for the ionization.
The ionization of a weak acid
The equilibrium expression for the above reaction is given below.
Where,
Smaller value of
Equilibrium in all acid – base reactions favours formation of the weaker base or weaker acid.

- Palmitoleic acid, a fatty acid with various pharmaceutical applications, is mainly obtained from macadamia nuts. The condensed structural formula for a triacylglycerol containing three palmitoleic acid units is provided below. Which of the following statements is NOT true regarding this triacylglycerol? O || CH,−O−C–(CH,)–CH=CH—(CH2)5–CH3 O || CH−O−C−(CH2)–CH=CH–(CH,)5–CH3 O CH,−O−C−(CH,)–CH=CH–(CH,)5–CH, O Its name is glyceryl tripalmitate or tripalmitin. O It is most likely to be liquid at room temperature. O It is an oil (not a fat). O It contains 3 molecules of the same unsaturated fatty acid.arrow_forwardIn a 0.28 mM aqueous solution of trimethylacetic acid (C4H9CO2H), what is the percentage of trimethylacetic acid that is dissociated?arrow_forwardIdentify the conjugate acid/conjugate base pairs for the structures below.arrow_forward
