 3) Soaps are made from a chemical reaction between an alkali (such as sodium hydroxide) and a fat or oil. This reaction is called saponification. Soaps are usually alkaline in nature, not acidic. 

Incorrect option

1) Soaps are acidic in nature: This statement is incorrect because soaps are actually alkaline in nature. As I mentioned in the previous answer, soaps are made from a chemical reaction between an alkali (such as sodium hydroxide) and a fat or oil. 

2) Soaps are made from animal fats: This statement is partially true. Soaps were originally made from animal fats, but today they can also be made from plant-based oils. Therefore, this statement is not completely correct.

4) Soaps are more effective than detergents in removing oil and grease stains: This statement is incorrect. Soaps have a disadvantage in that they can react with hard water to form scum, making it difficult to dissolve in water.
