What reaction takes place when palm oil is added to potash and foams are observed?

When palm oil is added to potash (potassium hydroxide), a saponification reaction occurs. This reaction involves the hydrolysis of the triglycerides in the palm oil, leading to the formation of glycerol and potassium salts of fatty acids (soap). The foaming observed is a result of the soap molecules trapping air, creating bubbles in the mixture. This process is typical in soap-making, where oils or fats react with an alkali to produce soap.
