1.	Why does table salt sometimes appear yellow in colour?
Answer» Answer: YELLOW colour in NaCI is due to metal excess defect due to which unpaired ELECTRONS occupy anionic sites, KNOWN as F-centres. These electrons absorb energy from the visible region for the excitation which makes crystal APPEAR yellow. Explanation: mark my answer as BRAINLIEST and also follow me
