The Phenolphthalein test paper is sensitive to Ammonia Vapours and thus is used to detect Ammonia leaks, for example, in refrigerators or air conditioners. Phenolphthalein detects Ammonia in solution from 3 - 5ppm. The test strip will turn a pinkish colour if Ammonia is detected.
INSTRUCTIONS:
NOTE: The solution must be water-based.
