Answer to Question #284657 in Chemistry for bless

Question

An oil X has a saponification Value of 100 and an Oil Y has a saponification

Value of 70. Which oil will have a high molecular weight and long fatty acid chain?

Answer 1

Saponification value or saponification number (SV or SN) represents the number of milligrams of potassium hydroxide (KOH) or sodium hydroxide (NaOH) required to saponify one gram of fat under the conditions specified.

A high saponification value indicates that the sample has a shorter fatty acid chain and a lower molecular weight.

Therefore, oil Y has a high molecular weight and long fatty acid chain.
