Interpretation:
It should be explained that the carboxyl group of lactic 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.

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

- Cream of tartar is a white powder sometimes used in baking. (It's what separates a tangy, chewy snickerdoodle from an ordinary cinnamon-coated sugar cookie. The acid in the cream of tartar gives snickerdoodles their distinctive tangy flavor, and the chew happens because cream of tartar prevents sugar in the cookie dough from crystalizing into crunchiness. Allrecipies.com) Cream of tartar (KHC4H4O6) is the conjugate base salt of tartaric acid (shown to the right). The Ka for another similar acid is 8.7×10-3.

- Ascorbic acid, H₂C6H6O6, is a diprotic acid usually known as vitamin C. For this acid, pk1 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 3.30 g. Calculate the molar concentration of ascorbic acid in the solution before it was evaporated. i 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 Marrow_forwardDescribe the trends in the physical properties of carboxylic acids, and contrast theirphysical properties with those of their salts.arrow_forwardH2PO3 Express your answer as a chemical formula.

- 75. Salicylic acid, HOC6H4CO2H, and its derivatives have been used as pain relievers for a long time. Salicylic acid occurs in small amounts in the leaves, bark, and roots of some vegetation (most notably historically in the bark of the willow tree). Extracts of these plants have been used as medications for centuries. The acid was first isolated in the laboratory in 1838. (a) Both functional groups of salicylic acid ionize in water, with Ka = 1.0 x 10-3 for the-CO2H group and 4.2 x 10-13 for the -OH group. What is the pH of a saturated solution of the acid (solubility = 1.8 g/L). (b) Aspirin was discovered as a result of efforts to produce a derivative of salicylic acid that would not be irritating to the stomach lining. Aspirin is acetylsalicylic acid, CH3CO2C6H4CO2H. The -CO2H functional group is still present, but its acidity is reduced, Ka = 3.0 × 10-4. What is the pH of a solution of aspirin with the same concentration as a saturated solution of salicylic acid (See Part a).arrow_forwardDefine the general structure of Compounds Containing a C=O Group ?arrow_forwardBy giving an example for each of the molecules of Alkyl halide, Aldehyde, Ketone, Carboxylic Acid, Ester, Anhydride, Amit, you can also identify the bond types (sigma -pi) and hybridization typesarrow_forward
