>Is Litmus Paper good enough to perform a pH test or do I need some kind >of speciality pH paper? Go to a medical supply place and ask for "pH test paper", not litmus paper. I found out the hard way that "litmus paper" comes in blue or pink and simply changes color in the presence of acid or alkali (can't remember offhand which color reacts with what) but "pH test paper" turns a specific color with a specific pH. === Dave Sacerdote davesas@tiac.net Resist or Serve.
