Dear All-
I have a really quick question here: The Phenopthalein solution I use
is a
1% in IPA (reagent grade from Sigma-Aldrich). This should be appropriate for
titrating WVO with a 1 normal (1g/l) solution of NaOH in DI water, with the
comversion being 1mL of NaOH added corresponding to 1 additonal gram of NaOH
needed above the 3.5 g required? I use 10 ML of the IPA/PHTH solution to 1mL
of WVO. I've worked out the chemistry, the numbers seem right, but I just
want to make sure that the 1% PHTH is about what everyone else out there
uses so I'm not getting screwball results.
Thanks
- Matt
And Keith, thank you very much for the JtF site.
