Thomas,
Thanks for the corection, I plead temporary insanity (actually I was distracted

I have some lab grade KOH that is near absolute also.
Can anyone give me a complete procedure to make a
comparison (Strength %) of one
make two solutions of the same concentration with the good and questionable
KOH. titrate against
any standard acid and compare.
