Calculate Saponification Value



Formula

The formula to calculate the Saponification Value (SV) is:

\[ SV = \frac{56.1 \times W}{V} \]

What is Saponification?

Saponification is a chemical reaction that involves the conversion of a fat or oil into soap and alcohol with the help of a strong alkali, typically lye or caustic soda. The process breaks down the ester bonds in the fat or oil, resulting in the formation of glycerol and fatty acid salts, which are the basic components of soap. This reaction is used in soap-making industries and is also a common laboratory technique in organic chemistry.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Saponification Value (SV):

\[ SV = \frac{56.1 \times W}{V} = \frac{56.1 \times 10}{20} = 28.05 \text{ mg KOH/g of fat} \]

The Saponification Value (SV) is 28.05 mg KOH/g of fat.
