Chapter 17, Problem 17.30P
Interpretation Introduction

Interpretation:

It should be explained that the ascorbic acid (Ka17.94×105) can exist whether primarly as a ascorbic acid or as a ascorbate anion under the given conditions in blood plasma.

Concept introduction:

Acid - ionization constantKa:

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 HA can be given as follows,

HA(aq)H+(aq)+A-(aq)

The equilibrium expression for the above reaction is given below.

Ka=[H+][A-][HA]

Where,

  Ka is acid ionization constant,

  [H+]  is concentration of hydrogen ion

  [A-]  is concentration of acid anion

           [HA] is concentration of the acid

pKa=logKapKb=logKb

Smaller value of pKa, stronger the acid, smaller the pKb, stronger the base.

Equilibrium in all acid – base reactions favours formation of the weaker base or weaker acid.

pH=log10[H+][H+]=10pH

Give at least 5 examples of biological compounds having a carboxylic acid functional group and identify the biochemical importance of each compound.
Ascorbic acid, H2C6H6O6, is a diprotic acid usually known as vitamin C. For this acid, pKa1 is 4.10 and pKa2 is 11.79. When 125 mL of a solution of ascorbic acid was evaporated to dryness, the residue of pure ascorbic acid had a mass of 4.14 g. Calculate the molar concentration of ascorbic acid in the solution before it was evaporated. i I M What was the pH of the ascorbic acid solution before it was evaporated? pH = i What was the concentration of the ascorbate ion, C6H6062, before the solution was evaporated? i M
Complete the following equation for the dissociation of butyric acid in water, so as to illustrate unambiguously that butyric acid is a weak acid: CH3CH2CH2COOH(aq)+ H20(1)
