Respuesta :
Answer: c weak acid
Explanation:
The faster the rate of leaving proton, the more strong the acid is. Due to the resonance structure of benzoic acid, power of leaving proton is restricted
Answer: The benzoic acid is a weak acid.
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses donates protons and thus forming conjugate base.
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
The chemical equation for the reaction of potassium benzoate with water follows:
[tex]C_6H_5COOK+H_2O\rightarrow C_6H_5COOH+KOH[/tex]
Here, benzoate anion is accepting a proton from water and is acting as conjugate base. Water is acting as conjugate acid.
The solution formed is basic solution because of the formation of potassium hydroxide.
When a strong base and weak acid reacts, it leads to the formation of basic solution.
Hence, the benzoic acid is a weak acid.
