Why refluxing is done in saponification?
Saponification is the process of producing soap. Refluxing is done in saponification to distill and remove fat droplets in order to complete the process.
Why mineral oil does not undergo saponification?
Saponification is the reaction between triesters and alcohol.Mineral oil is composed of paraffins and alkanes ,it does'nt contain ester group hence it does not undergo saponification
What is the formula to calculate saponification number?
Insoluble soaps are not likely to exist, they won't work when not IN water. For more you can trust on this: his process is called saponification: fat + sodium hydroxide -> Sodium salts of fatty acid (Soap) + glycerol
How are soap prepared?
Saponification
Why alcoholic potassium hydroxide is used for calculating saponification number of oil?
because alcohol is required for dissolving both KOH and lipid
Why do you think ethanol is used in saponification process?
Ethanol is added to hasten saponification.

Why does triacylglycerides with longer fatty acids have lower saponification number than those shorter fatty acids?
The saponification number is measure of the number of saponifiable sites (i.e. -esterified or unesterified- acyl groups, by reaction with OH-) per (AND HERE COMES THE CLUE)1 gram of tested sample.Just imagine you have 2 samples: L(ong) and S(hort) with the SAME amount of saponifiable sites per molecule (or mole), so they both react with the same amount of reactant (KOH or NaOH).If it were 'per mole' then the saponification numbers would be equal, won't they?BUT saponification number is per 1 gram, and as the Long chained triacylglycerides in sample L do have a higher molecular mass, there are less molecules (or moles, or sapon. sites) of them in 100 grams. Thus sample L has a lower saponification number than sample S.In this way the saponification number is a measure of the average molacular mass (also of average chain length) of triacylglicerides (i.e. normal fats) though under certain restrictions.
How do you calculate saponification number in fat acid containing palmitoleic stearic and butyric acid?

How do you saponification stearic acid?
Saponification is not applied to pure stearic acid; stearic acid esters are used.

What is the catalyst needed for saponification?
Thymol is a good catalyst in saponification. I personally used it during chem prac class :)
Between butter and margarine which one got higher saponification value?
margarine has saponification value more then butter
In which reaction is soap a product?
saponification
