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?
