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 nutritional value of curry?
The nutritional value will depend on the type of curry. The vegetables, spices, oil used will define the nutritional aspect.
Relationship between Free fatty acids and Peroxide value in edible oil?
When edible oil is exposed to air, it is attacked by atmospheric oxygen which yields free fatty acids in the oil and this leads to a process called rancidity. Peroxide value measures the amount of rancidity that has taken place. Ejike(swaggalicious)
Is alcohol and oil soluble in soluble?
All , Because the reaction between oil and alkali takes place only at interface and thus rate of the reaction is very slow . But when oil is dissolved in ethanol the saponification progresses well.
What is specific heat at constant pressure of honge oil?
The calorific value is 8 742 kJ/kg.
What is the saponification value of castor oil?
Saponification value is the amount of pure sodium hydroxide needed to saponified 100 grams of oil No. saponified castor oil is from 12.5 to 13 grams
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.
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
Saponification value of oil?
soponification value/number of an oil is defined as the milligram of KOH requird to sopanify fatty material present in 1gm of oil. sahil chhapola: for any enquiry about chemical engg. mail me at: sahilchhapola90@gmail.com
What is the role of ethanol in saponification?
ethanol allows oil to be able to mix with water.
Is there a different saponification value for an unhydrogenated oil than a fully hydrogenated oil?
Hydrogenation adds trans fats to the oil, which make no difference in the final product of soap. SAP value .144 seems to be the norm unless you go to soapcalc.com which has it at .142. This could be a major difference in lye, so it may take some hit or miss on the finished product.
How do you calculate saponification value?
(AOAC 920.160) In duplicate about 2g of the oil sample is added to a flask with 30ml of ethanolic KOH and is then attached to a condenser for 30 minutes to ensure the sample is fully dissolved. After sample has cooled 1ml of phenolphthalein is added and titrated with 0.5 M HCl until a pink endpoint has reached.

What are the products obtained by mixing caustic soda solution with vegetable oil?
This is just like the saponification of fats which produces soap.
How do you make oregano oil?
To make soap from scratch requires treating an oil or fat with an alkali, such as lye. Oregano is an additive that can be added to the soap after the saponification process is complete.
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
Why alcoholic potassium hydroxide is used for calculating saponification number of oil?
because alcohol is required for dissolving both KOH and lipid
