Then heat it for 7-10 minutes and then add 1 ml 1% or 5% phenolphthalein indicators and carried out titration Against KOH. Then a blank titration is done. Volume of KOH = KOH required for the test - KOH for blank. Say KOH for Sample = 0.8 KOH for blank = 0.2 Volume of KOH = 0.6 I then use the following formula ACV = Molarity of KOH * Volume of KOH * Molecular weight of KOH / sample weight. In this i Don't need to neutralise the alcohol as i carried out a blank experiment.

1. You can find the difference between normality and molary from google. 2. Purpose of stadardization is to know the exact concentration of any solution. 3. Normally ethanol is slightly acidic. So first titration of ethanol is done to make the ethanol neutral as if it does not interfare the acidity of our oil sample.

Irfan Ali, Thanks for your question. Yes adding Phenolphthalein twice is needed for this test. First time Phenolphthalein is added to carry out the neutralizing titration. Second time, it is added for the Acid Value determination titration. Both are needed because during boiling Phenolphthalein activity is lost in heat. So you have to add Phenolphthalein again before starting the Second & Final titration. We will try to upload a video for rancidity test very soon. Stay with us.

Some measures of free fatty acids use KOH as the standard while others use NaOH. To convert from KOH to NaOH, multiply by 40/56.11. Likewise, multiply by 56.11/40 for the opposite conversion. This ratio is just the molecular weight of NaOH to KOH.
