Phenolphthalein is a common pH indicator used in acid-base chemistry. But the history behind this compound is stranger than fiction! It was originally developed as a synthetic dye to compete with mauvine in the late 19th century. It was never used as a dye due to its pH sensitivity, which led to widespread use as a pH indicator. Phenolphthalein will change from colorless to pink once the pH is above 8, making it an ideal indicator for acid-base titrations. This color changing property also led t

Science Plus on Instagram: "Phenolphthalein is a synthetic indicator that shows the presence of a base. In a basic solution, it turns pink, while in an acidic solution it remains colorless. This activity demonstrates the same concept. When an acid and a base are mixed together, they neutralize each other’s effect, forming salt and water, due to which the color changes. This is called a neutralization reaction. To learn with such practical activities, join Science Plus. 📞 9549599909 &#x1f
