What is the saponification value of mentha arvensis essential oils?
Saponification value, or SAP value, is an approximated "value" assigned to the fats and oils used in soap making. Because essential oils contain no lipids, they will not saponify. Consequently, they have no SAP value.
What is value of oil painting signed marten?
I have a oil paining of a English cottage garden. had it for about 20 yrs signed MARTEN is it of any value ?
What is the value of an original peter cosslett oil painting?

Yes I have one but don't know the value?? Who does??
Want to know value of oil painting by h e fullen?
It is impossible to determine the value of a piece of art in this online format. Many factors determine the value of art. The best option is to have the piece appraised.
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.
What the saponification value of ocimum basilicum oil?
This value is between 4 and 10.
What is the importance of saponification value of oil?
The saponification value of oil indicates the amount of base needed to saponify a certain quantity of oil, which is important in soap making to determine the amount of lye required for the saponification process. It helps ensure that the right balance of oil and lye is used to create a stable and effective soap product.
Between butter and margarine which one got higher saponification value?
margarine has saponification value more then butter
Why mineral oil does not undergo saponification?
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.
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.
What is the saponification value of mentha arvensis essential oils?
Saponification value, or SAP value, is an approximated "value" assigned to the fats and oils used in soap making. Because essential oils contain no lipids, they will not saponify. Consequently, they have no SAP value.
Temperature related to saponification value?
Heat the flask on a steam bath.
Why alcoholic potassium hydroxide is used for calculating saponification number of oil?
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.
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.

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?
