Phenolphthalein is weak organic acid, inoratidzika sechena kana kuti yero zvishoma makristasi akanaka pane tembiricha. Hainhuhwi uye haina kunaka. Zvakaoma kunyungudika mumvura asi nyore kunyungudika mudoro (ethanol) uye ether. Iyo inonyungudutswa mumhinduro yedoro kuita iyo acid-base chiratidzo. Haina ruvara muacidic solution uye tsvuku mualkali solution kana alkali metal carbonate solution. Nekudaro, kana iri muconcentrated alkali solution, inoburitsa isina colorless trimetallic acid. munyu, ruvara rutsvuku runopera
