I made several titrations this evening on 1ml of new canola cooking oil to do some comparisons with,and learn as I go. I am astounded by the results. I have a wine acid testing kit with phenolphthalein and sodium hydroxide solution tested against turmeric and isoproypol solution.

I made the turmeric solution with a 91% isoproypol alcohol, the medical type not the red bottle found on the forum here. I also made a 3 gram : 3 liter solution of NaOH for testing with.



I made blank titrations from my wine test kit and the solutions I made, one drop of NaOH would make the color change I was looking for.

One ml of new oil would titrate at .2 ;(two tenths); does that sound right? If I get this right one liter of this oil would require 3.2 grams of sodium hydroxide to complete the reaction.

Am I outaa whack here or am I on the right track ?

Yes, that is the right track. New oil does not need to be titrated. 5 grams of NaOH per liter is the accepted baseline for new oil to get good conversion. For WVO you add the titration number to the 5 gram base for total grams/liter for your particular oil. HTH
