Hydrolysis of Trichloromethane with Aqueous KOH
Trichloromethane is also known as chloroform, which is a colorless, heavy, sweet-smelling liquid. When it is hydrolyzed with aqueous potassium hydroxide (KOH), it gives potassium formate as a product. Let us understand the reaction in detail.
The Reaction
Trichloromethane reacts with aqueous KOH to give potassium formate and potassium chloride as the products. The reaction is as follows:
CHCl3 + KOH → HCOOK + KCl
In the above reaction, CHCl3 is trichloromethane or chloroform, KOH is aqueous potassium hydroxide, HCOOK is potassium formate, and KCl is potassium chloride.
Explanation
The hydrolysis of trichloromethane with aqueous KOH is a nucleophilic substitution reaction. In this reaction, the hydroxide ion (OH-) acts as a nucleophile and attacks the carbon atom of the trichloromethane molecule. This leads to the displacement of the chlorine atoms by the hydroxide ions, resulting in the formation of potassium formate and potassium chloride.
Potassium formate is a colorless, aqueous solution that is used in the production of formic acid, which is an important industrial chemical. It is also used as a preservative for animal feed and as a de-icing agent for runways and roads.
Conclusion
Therefore, the correct option for the hydrolysis of trichloromethane with aqueous KOH is option A, which is potassium formate. The hydrolysis of trichloromethane with aqueous KOH is a nucleophilic substitution reaction, where potassium formate and potassium chloride are the products.
