Depending on its concentration.

Examples:

  1. 1.0 mol/L >> pH = 2.1
  2. 0.01 mol/L >> pH = 3.1

What is the dissociation constant for benzoic acid?

The dissociation constant (Ka) for benzoic acid is approximately 6.5 x 10^-5 at 25°C. This value indicates the extent to which benzoic acid dissociates into its conjugate base (benzoate ion) and a hydronium ion in solution. A higher Ka value indicates a stronger acid.


What should be the approximate pH and composition of aqueous system to dissolve benzoic acid?

To dissolve benzoic acid, the aqueous system should be slightly acidic with a pH around 2-3. This can be achieved by adding a small amount of hydrochloric acid to water. Benzoic acid is sparingly soluble in pure water but dissolves more readily in an acidic solution due to the formation of benzoate ions.


What is the significance of the benzoic acid rf value in chromatography analysis?

The benzoic acid rf value in chromatography analysis is significant because it helps to identify and separate different compounds in a mixture based on their relative migration distances. By comparing the rf value of benzoic acid to other compounds, scientists can determine the purity and composition of a sample.


A 50.0 ml sample of 0.43 m benzoic acid c6h5cooh is titrated with 0.50 m naoh calculate the pH at the equivalence point ka of c6h5cooh equals 6.5 10-5?

At the equivalence point, the moles of NaOH added will equal the moles of benzoic acid initially present in the sample. Since benzoic acid is a weak acid, it will partially dissociate in solution to produce benzoate ions and protons. At the equivalence point, all the benzoic acid has been converted to benzoate ions, resulting in a buffer solution of benzoate and its conjugate base. To calculate the pH at the equivalence point, you can use the Henderson-Hasselbalch equation, which considers the concentration of benzoate ions and benzoic acid to determine the pH of the solution.


Why is benzoic acid is in molecular form at pH of 2?

Benzoic acid is a weak acid, which means that its dissociation is reversible. C6H5COOH -----> C6H5COO- + H+ At pH 2, there are a lot of H+ ions in the solution. According to Le Chatelier's Principle, the equilibrium will shift to the left to favor the opposite reaction where Benzoic acid is produced, to reduce the amount of H+ in the solution. Therefore, an insignificant amount of benzoic acid will dissociate, while most of it remains in the molecular form.


Why is benzoic acid is extracted into ether then extracted into an alkali solution prior to being precipitated with strong acid in its preparation with grignard reagent?

When you're attempting to extract benzoic acid from other organic compounds, it is necessary to change its pH by adding a layer of an basic compound such as 1M NaOH so that the benzoic acid then can be separated from the organic layer within a separatory funnel. When in NaOH, the benzoic acid loses a proton and thus becomes its conjugate base (the benzoate ion). The benzoate ion is charged and thus become miscible in the aqueous layer. To extract benzoic acid (ie get it to precipitate out of solution), a strong acid such as HCl must be added to solution. After the extraction, lower the pH of the solution, and recrystalize (use ice after the recrystalization to get benzoic acid crystals to crash out).


How can you separate the mixture of chloroform aniline and benzoic acid?

One way to separate this mixture is through a process called liquid-liquid extraction. Aniline and benzoic acid are both water-soluble, while chloroform is not. By adding water to the mixture, the aniline and benzoic acid will dissolve in the water phase, leaving the chloroform to be separated out. The aniline and benzoic acid can then be recovered from the water phase by adjusting the pH of the solution.
