What is the Saponification value of Glycerin?
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.
What is the products of the saponification of tripalmitin?
Tripalmitin is a 16 carbon saturated fatty acid. Saponification is a reaction involving a strong base (ex: NaOH) and a fatty acid. The reaction yields a glycerol and 3 fatty acid salts. Therefore the reaction products are: glycerol: CH2(OH)--CH(OH)--CH2(OH) + 3 fatty acid salts: CH3--(CH2)14--COO(-) Na(+) + 3H2O Above is actually a summary of what is in reality a 2-step reaction: the fatty acid reacts with H2O first to yield a glycerol and 3 fatty acids; the fatty acids subsequently reacts with the alkaline (base) (NaOH) to yield 3 fatty acid salts and H2O
What is Salt of fatty acid called?
fatty acid salt, but I think you are looking for the word soap, or surfactant
What happens when a fatty acid is reacted with NaOH?
When a fatty acid is reacted with NaOH, a process called saponification occurs. This reaction results in the formation of soap, which is a salt of the fatty acid alongside glycerol. This reaction is commonly used in soap-making processes.
How will you prepare propane from sodium salt of fatty acids?
To prepare propane from the sodium salt of fatty acids, the process of saponification is typically used. Saponification involves reacting the sodium salt of fatty acids (soap) with a strong acid to split off the fatty acid, which can then be further processed to yield propane. The propane is obtained by decarboxylation of the fatty acid through a series of chemical reactions.
What happens when fatty acid reacts with NaOH?
what happen when fatti acid react with the NaOH
What is the Saponification value of Glycerin?

Why do saponification test on oil?
The saponification test is used to determine the amount of free fatty acids present in oil. During saponification, free fatty acids react with a strong base to form soap. By measuring the amount of base required for saponification, the free fatty acid content of the oil can be calculated, which is important for assessing oil quality for various applications.

Why alcoholic koH is used in test for saponification value in lipid?
To prevent formation of soap (by substitute the water with alcohol). But indeed KOH forms an ester with fatty acids. Explain a bit the role of alcohol please. Sometimes KOH is used to conjugate and Fatty acid. When lead to saponification and when to conjugation?
How do you saponification stearic acid?
Saponification is not applied to pure stearic acid; stearic acid esters are used.
What is volatile fatty acid number?
No one fatty acid is volatile.
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?
