AgI is used for producing artificial rain because Agl:
Correct answer: C. Has crystal structure similar to ice
- A. Is easy to spray at high altitude
- B. Is easy to synthesizes
- C. Has crystal structure similar to ice
- D. Is insoluble in water
Explanation
AgI has the crystal structure similar to ice. Hence it can act as a nucleus for the precipitation of the water molecules and causes rain.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
