What is the value of relative error if the absolute error is -10?
You need to know the measure in order to answer the question.
Absolute value is a measure of?
Absolute value is a measure of distance.
What are two products of saponification?
Ethyl Alcohol + Ethanoic Acid
What does the z-value in statistics have to do with the level of confidence?
A z-value by itself, has nothing to do with level of confidence.A z-value can be used to calculate probabilities of observing a result that is at least as far from the mean. That probability measure can be used to calculate the level of confidence but you need to be careful about using the one-tailed or two-tailed measures - as appropriate.A z-value by itself, has nothing to do with level of confidence.A z-value can be used to calculate probabilities of observing a result that is at least as far from the mean.

What is the measure of 7x plus 27?
The measure of 7x + 27 depends on the value of x.
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.
Between butter and margarine which one got higher saponification value?
margarine has saponification value more then butter
What the saponification value of ocimum basilicum oil?
This value is between 4 and 10.
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 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
Temperature related to saponification value?
Heat the flask on a steam bath.
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.
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?
Why do you think ethanol is used in saponification process?
Ethanol is added to hasten saponification.
What is the saponification value in an experiment?
determination of saponification value (or "saponification number", also referred to as "sap" in short) represents the number of milligrams of potassium hydroxide or sodium hydroxide required to saponify 1g of fat under the conditions specified. It is a measure of the average molecular weight (or chain length) of all the fatty acids present. As most of the mass of a fat/triester is in the 3 fatty acids, it allows for comparison of the average fatty acid chain length. If more moles of base are required to saponify N grams of fat then there are more moles of the fat the chain lengths are relatively small, given the following relation: Number of moles = mass of oil/relative atomic mass Handmade soap makers who aim for bar soap use NaOH sap values which are derived from the saponification value calculated by laboratories (KOH sap value). To convert KOH values to NaOH values, divide the KOH values by the ratio of the molecular weights of KOH and NaOH (1.403). Standard methods for analysis are for example: ASTM D 94 (for petroleum) and DIN 51559. The calculated saponification value is not applicable to fats and oils containing high amounts of unsaponifiable material, free fatty acids (>0.1%), or mono- and diacylglycerols (>0.1%).
What is the meanig of saponification number?
The saponification number is a measure of the amount of alkali needed to saponify a certain weight of fat or oil. It indicates the average molecular weight of the fatty acids present in a sample. A higher saponification number indicates a higher average molecular weight of the fats or oils.
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.
