Which one of the following is NOT correctly matched?
- ASilver bromide - artificial photosynthesis
- BSilver iodide - artificial rain
- CLithium bicarbonate - treatment of rheumatism
- DMilk of magnesia - antacid
Show answer and explanation
Correct answer: (a) Silver bromide - artificial photosynthesis
Explanation
Silver bromide (AgBr) is light-sensitive and used in photographic films, not in artificial photosynthesis, so the pair is wrong.
Silver iodide (AgI) is correctly used for cloud seeding to make artificial rain.
Lithium bicarbonate treats rheumatism, and Milk of magnesia [Mg(OH)2] works as an antacid.
