It aids in the detection of the presence of glycerides of fatty acids containing less than 16 to 18 carbon atoms. It can also indicate adulteration of the oil with unsaponifiable matter, such as mineral oil.

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
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?
The formation of an ester bond between glycerol and a fatty acid in a triglyceride release what molecule?
It is hydrolysis, the hydrolysis in basic medium is also known as the Saponification process.
What impurities were removed from the soap by washing it on the Buchner funnel?
If u were doing the experiment in which you first heat the fatty acid to saponification, then washing the soap on a buchner funnel with cold water will remove the glycerine.
What happens when fatty acid reacts with NaOH?
what happen when fatti acid react with the NaOH

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.

Substance made when alkalis react with oils?
The process is called saponification, with which you make soap.
How do the number of hydrogen atoms compared to the number oxygen atoms in each fatty acid?
Bec in each fatty acid the o has a bond with h I think?!

What are two products of saponification?
Ethyl Alcohol + Ethanoic Acid
