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

The sulfuric acid was clear at first, but suddenly turned orange after being poured into the beaker. This happened because the glassware wasn’t properly cleaned, and leftover chemicals contaminated the solution. Even small residues can change your results. Always clean and sterilize your equipment before use #fyp #kimia #chemistry #laboratorium In chemistry, cleanliness isn’t optional — it’s essential.
