Hello Ray, Bill
Hello Bill:
Firstly, I apologize to the actual author, I simply cut and paste
into a file of important notes:
That's okay, I'm the author. I'd have just given the url, so this is
better. Anyway, this is the url:

"KOH is not as strong as NaOH -- use 1.4 times as much KOH (actually
1.4025 times). Titration is the same, just use a 0.1% KOH solution
instead of NaOH solution, and use 1 gm of KOH for every milliliter of
0.1% solution used in the titration. But instead of the basic 3.5
grams of NaOH lye per liter of oil, use 3.5 x 1.4 = 4.9 grams of KOH.
So, if your titration was 5 ml, use 5 + 4.9 = 9.9 gm KOH per liter of
oil."
"...One more complication -- check the purity of your KOH, it's
generally not as pure as NaOH. Anhydrous grade KOH flake is usually
about 92%, sometimes less -- check the label. We use half-pearls
assayed at 85%. Adjust the basic quantity accordingly: the basic 4.9
grams would be 5.8 (5.775) grams for 85% KOH, or 5.3 (5.33) grams for
92% KOH."

Hello Keith and all,
I have a question regarding titration with KOH. When making your titration
solution (1 g KOH/ L distilled water) is itn necesary to adjust for
the percent
of your KOH, i.e. 90.5%? I am making the adjustment for the basic
3.5 grans NaOH
to 5.4 grams KOH. However, I made no adjustments when making the titration
solution.
Any help is appreciated.
Bill Clark
