Рет қаралды 187,949

Күн бұрын

Saponification value is defined as the amount of potassium hydroxide (KOH) in milligrams required to saponify one gram of fat or oil. It is a very important testing parameter for oil or fat samples. This video represents a complete procedure for the determination of Saponification Value of an oil or fat sample.

when i did this experiment, i mixed 3.4g KOH+ 2ml distilled water+rest of ethanol to make upto 100 ml volume(0.5 N solution). I made this ethanolic KOH using directions I found on the web. Then I directly dissolved 1g oil sample in 50 ml of prepared mixture. It got clear only in 5 minutes. I prepared 0.5 N Hcl by adding 10ml in 250 ml water(37% Hcl). When I titrated, I was getting a very large saponification value(about 500). The formula I used is [(blank titre-sample titre)*56*normailty of KOH]/weight of sample. Can you tell me what am I doing wrong? And what is the purpose of the methods u have used like use of aluminium foil and initially boiling koh with ethanol?

Sample flask contains sample, thats why during saponification, the concentration of KOH in sample is decreased, thus HCl is needed more in compared with blank.
