" acid value (or "neutralization number" or "acid number" or "acidity") is the mass of potassium hydroxide (KOH) in milligrams that is required to neutralize one gram of chemical substance."-wikipedia
Oils are made of triglycerides. During processing some amount of oil can be break down to fatty acids and glycerol s.This amount of fatty acids should be less.
Every oil has a specific acid value range. It shows the amount of free acids available in oil.So it is used as a Quality parameter of oil.
as a example acid value of coconut oil should be below 3mg. otherwise its consider as a poor in quality

What is the effect of acid value on the working efficiency of a lubricant?
A higher acid value in a lubricant can lead to increased corrosiveness and deteriorate the lubricant's ability to protect machinery surfaces. This can result in increased wear and tear on machine parts, ultimately reducing the lubricant's effectiveness and potentially causing damage to equipment. Regular monitoring and maintenance of acid value is important to ensure optimal lubricant performance.
What is the pKa value of benzoic acid?
The pKa value of benzoic acid is approximately 4.2.
Acid with a small k value would be a?
weak acid
What is the pKa value for Hydroastatic acid and Periodic acid?
There are no accurate pKa value of these two, extremely STRONG acids, any value of >> 1000 (up to >> 1.0*10+9) will do.
What is the pKa value of 2-nitrobenzoic acid?
The pKa value of 2-nitrobenzoic acid is approximately 2.3.
Why is Ka an important value in chemistry?
For a weak acid, the value of Ka gives one an indication of the degree to which that weak acid will dissociate. This then gives one an idea of the acidity of that weak acid, and it can be easily compared to other weak acids.
What is the use of acid value?
The acid value is a measure of the acidity of many organic materials.
How does neutralization change the pH value of an acid?
When an acid is neutralized, its pH value is changed to be around 7 and it is no longer an acid.

What is the formula to determine the acid value of an oil?
ACID VALUE=Normality OF KOK or NaOH*5061/w
What Is the pH value of hydrochlorlic acid?
The pH value of an acid solution depends on its concentration and the temperature of the solution.
What is the pKa value of 2-nitrobenzoic acid?
The pKa value of 2-nitrobenzoic acid is approximately 2.3.
What is the pKa value of o-toluic acid?
The pKa value of o-toluic acid is approximately 4.21.
What does acid is important?
Acid Rain
