phenol is insoluble in NNAHCO3 solution while acetic acid is soluble.give reason.

Carboxylic acids are strong enough acids to react with NaHCO3 or with NaOH. Acetic acid is a carboxylic acid.

Phenol will react with NaOH but not NaHCO3 because it is too weak.
In fact, that is a test in organic chemistry to determine if it is a carboxylic acid or not. Extract with NaOH and you get all of the acids. Extract with NaHCO3 and you get the carboxylic acids but not the other weaker organic acids.

acetic acid is strong enugh to react with NAHCO3 while phenol is not soluble in NAHCO3..because it is weaker acid

The solubility of a substance in a particular solution depends on the nature of the solute and solvent, as well as their intermolecular interactions. In the case of phenol and acetic acid, their different solubilities in sodium bicarbonate (NaHCO3) solution can be explained by the differences in their chemical properties.

1. Phenol: Phenol is relatively insoluble in NaHCO3 solution. This can be attributed to the fact that phenol is a weak acid, and it does not readily ionize in water. In other words, it does not easily donate a proton (H+) to form phenolate ions (C6H5O-). Since NaHCO3 is a basic solution, it contains bicarbonate ions (HCO3-) that can accept protons. However, the weak acidic nature of phenol limits its ability to donate protons, resulting in poor solubility.

To determine if a substance is soluble in NaHCO3 solution, you can perform a simple solubility test. Add a small amount of the substance to the NaHCO3 solution and observe if it dissolves or forms a precipitate. If it remains undissolved, it indicates insolubility in NaHCO3.

2. Acetic acid: Unlike phenol, acetic acid is highly soluble in NaHCO3 solution. This can be explained by the fact that acetic acid is a weak acid, similar to phenol. However, acetic acid can readily donate a proton to form acetate ions (CH3COO-). In a basic solution like NaHCO3, with bicarbonate ions that can accept protons, acetic acid readily reacts to form soluble acetate ions and carbon dioxide (CO2) gas.

To determine if acetic acid is soluble in NaHCO3 solution, perform the same solubility test described before. Add a small amount of acetic acid to the NaHCO3 solution and observe if it dissolves completely to form a clear solution.

In summary, the difference in solubility between phenol and acetic acid in NaHCO3 solution can be attributed to their varying abilities to donate protons and form soluble ions in basic conditions. Phenol's limited acid ionization results in low solubility, while acetic acid's relatively efficient ionization makes it highly soluble in NaHCO3 solution.
