Phenolphthalein is another pH indicator. In solution, it's colorless, but its ion is fuchsia. Ionization changes the compound's color. It is colorless between pH of 1 and 8.2, fuchsia between 8.3 and 10, and colorless above 10. At pH less than 1, the color turns orange-red, as in sulfuric acid. However, not all strong acids will exhibit this color. What are the chemical equations that show the color change of dropping Phenolphthalein to NaOH, KOH, and a very acidic solution from: NaOH and KOH Colorless to Fuchsia Fuchsia to Colorless Very acidic solution Colorless to red-orange

Phenolphthalein is another pH indicator. In solution, it's colorless, but its ion is fuchsia. Ionization changes the compound's color. It is colorless between pH of 1 and 8.2, fuchsia between 8.3 and 10, and colorless above 10. At pH less than 1, the color turns orange-red, as in sulfuric acid. However, not all strong acids will exhibit this color. What are the chemical equations that show the color change of dropping Phenolphthalein to NaOH, KOH, and a very acidic solution from:
- NaOH and KOH
- Colorless to Fuchsia
- Fuchsia to Colorless
- Very acidic solution
- Colorless to red-orange
