15 reactions | Phenolphthalein works somewhat differently as it is naturally colorless but turns pink in alkaline solutions. The compounds remains colorless throughout the range of acidic pH levels but begins to turn pink at a pH level of 8.2 and continues to a bright purple in stronger alkalines. #uetss #we_make_the_change | UET Science Society | Facebook
