Hello,
I made a testbatch with clean sunfloweroil and first quality test was good.
I washed the solution with water and let it settle for a week. i did this 3
times and then i filtered the biodiesel. Yhe biodiesel looked crystal clear.
I tested the pH and it was 2.5! What happend here? How is
How did you measured the pH?

Marc, How did you test the pH ? The problem here is that pH is only
strictly defined in an aqueous solution.
What I am saying is that the pH most likely is not low, rather the way
you are measuring is meaningless.

Marc,
maybe you are measuring the color of the moon instead of the PH of your bio
diesel. ;-)
Ph is a measure for the H+ ( or H3O+) concentration in aqueous environment,
thus in water, or at least in an polar solvent ( like ethanol/methanol),
you can NOT measure PH with PH-paper test strips
Hello Bruno,
I would have thought the test paper would eventually react and work though
slower. Why would it not function?
