Makes the litmus test even stranger...
My guess is it is not litmus test per se. If you read my first post, I stated "The sample was then tested with a strip of paper that looked similar to a lithmus paper". Acidity testing would not be able to detect many explosives and looking for very small amounts of corrosives seems like a waste of time.
