The solubility of benzoic acid (HC 7 H 5 O 2 ), is 0.34 g/100 mL in water at 25°C and is 10.0 g/100 mL in benzene (C 6 H 6 ) at 25°C. Rationalize this solubility behavior. ( Hint: Benzoic acid forms a dimer in benzene.) Would benzoic acid be more or less soluble in a 0.1- M NaOH solution than it is in water? Explain.

The solubility of benzoic acid (HC7H5O2),
is 0.34 g/100 mL in water at 25°C and is 10.0 g/100 mL in benzene (C6H6) at 25°C. Rationalize this solubility behavior. (Hint: Benzoic acid forms a dimer in benzene.) Would benzoic acid be more or less soluble in a 0.1-M NaOH solution than it is in water? Explain.
Interpretation Introduction
Interpretation: The solubility of Benzoic acid should be explained.
Concept Introduction:
Solubility:
- The solubility of the solute is depends on the many factors and the polarity of solute is one of that.
- The same polarity of solvent is favored the solubility of solute.
- The polarity of the compound is determined by its structure.
Explanation of Solution
Record data from given:
To explain the solubility of benzoic acid in Water and Benzene.
Fig 1 Fig 2
- The benzoic acid is containing oxygen with lone pairs see Fig 1 and it is having electro negativity so it will make a hydrogen-bonded with another molecule to form a dimer
