Question

The saponification value is given by ______

(a) Saponification value = (volume of KOH +NKOH+56)/wt of the oil taken

(b) Saponification value = (volume of KOH * NKOH/56)/wt of the oil taken

(c) Saponification value = (volume of KOH * NKOH*56)/wt of the oil taken

(d) Saponification value = (volume of KOH – NKOH-56)/wt of the oil taken

I have been asked this question by my school principal while I was bunking the class.

This intriguing question originated from Saponification Value topic in division Lubricants of Applied Chemistry

Answer 1

Correct choice is (c) Saponification value = (volume of KOH * NKOH*56)/wt of the oil taken

The explanation: The saponification value is given by Saponification value = (volume of KOH * NKOH*56)/wt of the oil taken. So, to determine the saponification value first we need to know the volume of KOH utilised.
