Answer 2

• The chemical compound phenolphthalein is usually abbreviated as "HIn" or "phph" and has the formula C20H14O4. Phenolphthalein is a widely used indicator in acid–base titrations. It turns colourless in acidic solutions and pink in basic ones. It's a sort of dye called phthalein.
• Phenolphthalein is insoluble in water and must be dissolved in alcohols before being used in research.
• It's a weak acid that loses hydrogen ions when it dissolves in water.
• When phenolphthalein is combined with a base, it produces three colours: colourless nonionized phenolphthalein, orange protonated phenolphthalein ion, and fuchsia deprotonated phenolphthalein ion.
