Question
Explain how turmeric paper is made and used as an indicator.
✓
Answer
→ Turmeric paper, a simple and natural indicator, is crafted by mixing turmeric powder with water to form a paste.
→ which is then evenly spread on filter paper or paper towels and left to dry completely.
→ Once dried, the turmeric-coated paper is cut into strips, ready for use as an indicator. To test a substance, a turmeric paper strip is dipped into the solution, and any color change is observed.
→ In acidic solutions, the paper remains yellow or turns slightly lighter, while in basic solutions, it turns a distinct reddish-brown.
→ This makes turmeric paper particularly useful for identifying basic substances due to its noticeable color change, though it is less effective for identifying acids, where the change is minimal.
