Solution

Given data:                  volume of oil          = 9ml

                                Volume of KOH        = 1.5ml

                             Normality of KOH       = 0.04N

                          To find: Acid value

                    Formula: Acid value    ` =("Volume of  KHO "xx "Normality of  KOH" xx 56 )/("Weight  of oil") ` mg/gm

                  Solution: Acid value        = `(1.5 xx 0.04 xx 56)/9` mg/gm

                                                                = 0.373 mg/gm

                           Acid value of the oil is 0.373 mg/gm.
