i thank you for your help Mr. Mahoney.
the known variables will be:
pH of the base (by reference measurement)
pH of the Oil (by measurement)
volume of the oil (by external input)
the unknown will be:
volume of base needed to reach a pH of 8.4
i dont really need numbers, just a formula that i
Hey Jason;
If you are bent on doing this, why not approach it from a different
angle? Make a system that imitates what you do yourself, instead of
trying to do it numerically just make a system that does what you do.
It could all be done by way of gravity feed and counting drops by use of

It's been a few years since I took chemistry, but I seem to recall
that pH is a logarithm of the number of H+ ions in solution. At least
in an aqueous solution. That definition might not hold up under a
non-aqueous solution such as methoxide. But if you convert from pH to
moles of H+ or OH-

If you are titrating to a specific pH (say 8.4) and want to automate it

Jason Katie,
The problem is that pH alone does not tell the complete story. The amount of
base
required to reach a pH of 8.4 to 8.6 will vary with each batch and depends on
the
concentration and reactivity of each chemical compound in the oil and the purity
of the base. This is why we do a

Mr. Street,
how does semi local sound? there are almost a dozen towns of more than 1,000
but less than 10,000 people spread over two counties in the (rather
inaccurately named, i might add) Quad Cities, plus the original four cities,
and until the eighties (surprise) there were large farm

I think you should 'manualize' the process.

Sorry - I don't follow...
You mean do it manually? And if so - to what advantage?
