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-

Jason Katie, If you are titrating to a specific pH (say 8.4) and want to automate it then a standard waste water pH controller operating a small flow rate pump designed to handle the titrant (the titrant would be liquid caustic, yes? If so I recommend a teflon pump) should do the trick. You

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
