What is the degree of saponification?
Saponification is the process of creating soap. It typically involves reacting a strong alkaline (such as sodium hydroxide, potassium hydroxide, etc.) with a fatty acid or oil. The strong base reacts with the fatty acid to create a salt with a long hydrocarbon chain left over from the fatty acid or oil. Here's the reaction (using lye as an example): (hydrocarbon chain)-COOH + NaOH --> (hydrocarbon chain)-COONa + H2O When the cation bonds with the fatty acid/oil, it creates a new substance that possess the hydrophilic properties of the lipid hydrocarbon chain as well as the hydrophilic properties of the alkali metal (the sodium atom). Therefore, it can mix with both hydrophobic AND hydrophilic substances. Thus, if you need to wash away something greasy (hydrophobic), the hydrophobic chain of the soap will mix with the greasy substance, and a polar substance (such as water) can mix with the hydrophilic end of the soap as well...allowing you to mix grease with soap with water...and wash it away.
What is the use of acid slurry in making soap?
The synthesis of soap, which is known to chemists as saponification, is done with fat, and bases such as sodium hydroxide (NaOH). It does not involve acid slurry. Although, if you were going to try this at home, it might be a good idea to keep some mild acid on hand to neutralize the base, if your reaction gets out of hand or spills on your skin while it is still at a very high pH level.
Is metabolizing fat a part of chemical change?
Yes. When fat is metabolized, it is broken down by a chemical reaction called hydrolysis.
Is emulsification an anabolic reaction or a catabolic reaction?
Emulsification is the process of breaking down large fat globules into smaller, uniformly distributed particles. It is an example of catabolic reaction.
What is a union of glycerol and fatty acids to form fat an example of?
dehydration reaction
What type of saponification reaction takes place in the human body?
Saponification takes place in places where fat is stored in the human body.
Why is the hydrolysis of fat called saponification?
The term "Saponification" is an indication of what this reaction originally was used for: making soap. By boiling animal fat or lard with either potassium hydroxide or sodium hydroxide, the reaction, hydrolysis, produced glycerol and soap.
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.
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
What compounds are derived from lipids?
Steroids and fat-soluble vitamins are classified as derived lipid since they can be inactivated by saponification reaction, the structure therefore is not ester type but it is an alcohol type.
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 happens when fatty acid reacts with NaOH?
what happen when fatti acid react with the NaOH

Which fat sample will require more KOH for complete saponification cottonseed oil or the same mass of lard?
The lard sample will require more KOH for complete saponification. This is because lard is a saturated fat, and therefore the molecules are more closely packed together. This means that there are more bonds that need to be broken in order to saponify the fat.

What is a glyceral?
Glycerol is a sweet, clear liquid obtained from oils and fat as a byproduct of saponification and used as a solvent, antifreeze, or plasticizer,
What is products of the saponification of NaOH?
Saponification is the hydrolysis of fat in presence of caustic soda (NaOH), the products are Soap and Glycerin CH2-CO-R1 CH2-OH R1-COONa | | CH-CO-R2 + 3NaOH --------> CH-OH + R2-COONa | | CH2-CO-R3 CH2-OH R3-COONa (Fat) (Glycerin) (Soap)
