Hey, I was wondering if any of you chemist-types knew how I would make a hair rinse using cream of tartar instead of vinegar? I'm out of vinegar, but I also never took chemistry, so I'm unable to figure out how to make a similar-acidity solution using the tartaric acid that comes out of a solution of cream of tartar in water. Wikipedia says that a saturated solution of potassium bitartrate (cream of tartar) has a pH of about 3.55, but I don't know how much cream of tartar in how much water makes a saturated solution.

Any help?
