Question

Write the names of two important substances used in the preparation of soap?

Answer 1

Soaps are prepared by hydrolysis of fat using sodium or potassium hydroxide.

Soaps are also prepared by direct neutralization of fatty acids using sodium hydroxide or sodium carbonate.

$\underset{\text{higher fatty acid}}{R-COOH}+NaOH\to \underset{\text{soap}}{R-COONa}+H_{2}O$
