it is defined as the number of miligrams of potassium hydroxide or sodium hydroxide required to sponify 1 gram of the fat or oil
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
Alcoholic potassium hydroxide is used for calculating the saponification number of oil because it helps to break down ester bonds in triglycerides to form soap and glycerol through saponification. The amount of alcoholic potassium hydroxide required to completely saponify a given amount of oil is used to determine the saponification number, which is a measure of the average molecular weight of the fatty acids in the oil.
Mineral oil is a non-polar compound with long hydrocarbon chains and lacks the functional groups needed for saponification, such as ester functional groups found in triglycerides. Saponification is a reaction that involves breaking down ester bonds in fats and oils, so without these bonds, mineral oil cannot undergo saponification.
Glycerin and soap are the bye-products of saponification. The saponification value of glycerine are values of the percentage of lye it takes to convert one unit of fat, oil or fatty acid into glycerin.
The saponification process in soapmaking usually takes between 24 to 48 hours to complete. During this time, the oils and lye solution react to form soap through the chemical reaction of saponification. Once saponification is complete, the soap is left to cure and harden before it is ready for use.

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.
Ethanol is added to hasten saponification.

Saponification is not applied to pure stearic acid; stearic acid esters are used.
margarine has saponification value more then butter

A fraction is part of a whole number and it comes from a Latin word meaning broken part.
No, a magnet cannot create saponification. Saponification is a chemical reaction that typically involves a base (like lye) with fats or oils to produce soap. Magnets do not play a role in this chemical process.
