Butter when fresh is in the state of being a triacylglycerol, 3 fatty acid chains attached to a glycerol backbone. When a butter ages it undergoes a process of oxidation called lipolysis. This is where the fatty acid chains split from the glycerol backbone the result of which is the formation noticeably off flavours being present in the butter. Hence the point of using old and new butter is that the old butter should have a higher acid value than the fresh butter

What pH value indicates an acid?
A pH value less than 7.0.
How can you identify if a chemical is an acid?
A chemical can be identified as an acid by testing its pH. A pH value less than seven is considered acidic, while a pH value greater than seven is considered to be a base, or alkaline. Pure water has a pH value of seven.
Why is methanoic acid more acidic than benzoic acid?
We would certainly expect benzoic acid to be more acidic than methanoic acid, due to stabilisation of the benzoate anion caused by the delocalisation of the electrons on the oxygen atom over the benzene ring. However, in practice, it is found that methanoic acid is actually more acidic than benzoic acid(has a greater Ka value). This is because methanoic acid is more soluble in water than benzoic acid, so there is greater ionisation of methanoic acid in water than benzoic acid.
Do all acid has pH value less than 7?
The definition of acidic is having a pH less than 7.
Which of properties does lithium have a larger value than potassium?
The potassium is larger radius because it has more electron shells.
Why use old and new butter in acid value test?
An acid value test is preformed on butter to gauge the levels of free fatty acids. Butter when fresh is in the state of being a triacylglycerol, 3 fatty acid chains attached to a glycerol backbone. When a butter ages it undergoes a process of oxidation called lipolysis. This is where the fatty acid chains split from the glycerol backbone the result of which is the formation noticeably off flavours being present in the butter. Hence the point of using old and new butter is that the old butter should have a higher acid value than the fresh butter.
Why lower acid value is better than higher acid value?
nano technology in chemistry?
What if actual value - measured value is negative?
Then the measured value is larger than the actual value.
What pH value indicates an acid?
A pH value less than 7.0.
How is 219 bigger than 209?
It has a larger value.
What is the larger number 0.8 or the number 2?
2 has a larger value than 0.8.
How much larger is the value of 2 in 52346 than it is in 246?
ten times larger
How many times larger is the value 350000 than 350?
It is 1000 times larger.
How many times larger is the Value 25000 than 250?
100 times larger
Which is bigger 16.1 or 16.02?
16.1 is larger cause if the 1 is in the tenths then it has a larger value and 2 which is in the hundredths is a smaller value remember tenths are larger behind the decimal and more than tenths is a smaller value behind the decimal
The sample variance is always smaller than the true value of the population variance is always larger than the true value of the population variance could be smaller equal to or?
yes, it can be smaller, equal or larger to the true value of the population varience.
Can a joint probability have a value greater than 1?
A joint probability can have a value greater than one. It can only have a value larger than 1 over a region that measures less than 1.
