Be careful with phenolphthalein. It is the active ingredient in Exlax. Kirk
-----Original Message----- From: Jonathan Pennington [mailto:[EMAIL PROTECTED] Sent: Sunday, April 21, 2002 5:53 AM To: biofuel@yahoogroups.com Subject: [biofuel] Titration point This may sound like a stupid question, there are such things in my book. If I'm using a pH meter instead of Phenolphthalein to titrate my WVO, should I just add the lye/water solution until I reach 8-9 pH? The real question is, am I merely going for a slightly basic solution or is there a certain *specific* pH that I'm trying to reach. By the way, for any others who would email me about my buying a pH meter and the foolproof 2-stage method. I realize that it exists and that I don't need to titrate using it. I am *choosing* not to use it because I want to titrate, and want a single step. Just thought I'd save some people the trouble of emailing me.
