Hi,
As a student of chemical engineering I can tell you the following: > I think the chemical is called Phenolpthalein, (I think),[...] and it is a > chemical indicator. Yes, it is called Phenolphthalein and yes, it's an indicator. > (Vinegar is acidic, and Baking soda is basic). Vinegar will cause Phenolphthalein to become clear while baking soda wil make it go purple. What you could also try (no guarantee!) would be to use any colorant (ink, iodine...) to let the water go dark and have chlorine or hydrogenperoxide (H2O2) make it clear again. Always prepared for Jesus. -------------------------------------------- Stefan Fischer (Fani) Lieutenant-Commander, OP #78 Moetzingen/Germany http://www.royal-ranger.com -------------------------------------------- _______ This mailing list is dedicated to the glory of God.
