Write a short on saponification value

Hint: During this question consider the method of formation of soap from the reaction of triglycerides in fat with aqueous $NaOH$ or $KOH$ . This process is termed saponification and therefore the reactants help within the process of formation of soaps.

Complete step by step answer:
In the word saponification, the word 'Sapo' is really a Latin word which suggests soap. In general words, we will say the method of creating soap is named saponification. Soaps are long chains of sodium and potassium salts of fatty acids. In terms of chemistry, saponification is often defined because the reaction of an ester with water and base like or to offer alcohol and sodium or potassium salt of the acid. The oils which undergo the saponification reaction are referred to as saponified oils. Saponified oils are mixed with caustic soda and water. a measure of the totally free and combined acids, especially during a fat, wax, or resin, expressed because the number of milligrams of potash required for the entire saponification of 1 gram of a substance

Additional Information:
1. It tells you about the length of the carbon chain in carboxylic acid getting used for saponification.
2. Saponification value of these fatty acids which have a really long carbon chain is usually low.
3. Saponification value is going to be higher for fats containing short carbon chains. for instance, the saponification value for butter is 230-240 while for human fat it's 195-200.
4. It gives a thought about the typical relative molecular mass of the fat or oil utilized in saponification.

Note:
 Saponification reaction involves the reaction of sodium or potassium hydroxides with triglycerides (esters) to supply glycerol (alcohol) and carboxylic acid salts of potassium or sodium. The carboxylic acid salts of potassium or sodium are referred to as 'soaps'.
