ACID VALUE=
Peroxide is used to determine the acid value of vegetable oil using primary standard. Oils with high degree of unsaturation are most susceptible to autoxidation.
Oil of Vitriol is an old name for sulfuric acid (H2SO4). Sulfuric acid's structural formula is:
The standard acid value of peanut/grondnut oil is about 3.5 to 4.0%
The purpose of checking the acid value of the lubricant oil is that it determines the efficiency.
Oil of vitriol is another name for sulfuric acid, which has the chemical formula H2SO4.
The acid value of coconut oil should be approximately 1.0 - 2.0%. Coconut oil can be found in most grocery stores.
Blue vitriol is an obsolete name for copper(II) sulphate - CuSO4.
The acid value of rancid coconut oil can vary, but it typically indicates a higher level of free fatty acids due to the breakdown of triglycerides. Generally, fresh coconut oil has an acid value of less than 0.5 mg KOH/g, while rancid coconut oil can have an acid value significantly above this threshold, often exceeding 1 mg KOH/g. This increase in acid value is a key indicator of spoilage and deterioration in quality.
Oil of Vitriol (also known as sulfuric acid) is mainly used for car batteries, ore processing, fertilizer manufacturing, oil refining, wastewater processing and chemical synthesis. But the main use is in car batteries. The chemical formula of oil of vitriol is H2SO4.Source: Wickipedia

The acid value of oil indicates the amount of free fatty acids present, which can impact the oil's quality by affecting its flavor, shelf life, and stability. Higher acid values can lead to rancidity, off-flavors, and decreased stability of the oil. Therefore, oils with lower acid values are generally considered to be of higher quality.
