Question

What do you observe when acetic acid neutralizes ${\text{FeCl}}_3$ solution?

Answer 1

Acetic acid:
1. Acetic acid, also known as Ethanoic acid has the chemical formula $C{H}_{3}COOH$.
Neutralization of ${\text{FeCl}}_3$:
1. Neutralized Ferric Chloride (${\text{FeCl}}_3$) is used in the test between Phenols and Alcohols.
2. Ferric Chloride is neutralized by Acetic acid, where Ferric Acetate is formed as a product.
3. The reaction is given below:
$3{\text{CH}}_3\text{COOH (l)}+{\text{FeCl}}_3\left(s\right)\to {\left({\text{CH}}_3\text{COO}\right)}_3\text{Fe (s)}+3\text{HCl (l)}$
4. In the neutralization of Ferric acid, red wine coloration can be seen.

Red wine coloration is observed when Acetic acid neutralizes ${\text{FeCl}}_3$ solution.
