Saponification’s Effects on Soap
The Saponification process induces significant changes in the soap molecule:
- Saponification converts carboxylic acid group (COOH) into a carboxylate ion (COO–) to form a salt.
- This means that the soap molecule undergoes increased water solubility, facilitating easy rinsing and removal.
- Sodium or Potassium ions (Na+or K+) initially attached to the soap molecule are eliminated during saponification. This results in the soap molecule acquiring an electric charge.
- In addition, the sodium or potassium ions (Na+or K+) attached to the soap molecules are also removed, so the soap molecule is now charged.
- Here, soap bubbles show an inherent attraction to each other and to objects possessing opposite charges. This charged nature enhances the effectiveness of soap.
Saponification
Saponification word originates from the Latin word ‘Sapo,’ meaning soap. It is the general process of the creation of soap. Soaps are the sodium salt or potassium salts of a long chain carboxylic acid or glycerol which has cleansing properties in water.
Saponification refers to the interaction of an ester with water and a base like NaOH or KOH, resulting in the formation of alcohol and the sodium or potassium salt of an acid.
