Current Question (ID: 18442)

Question:

$\text{Silver iodide is used for producing artificial rain because AgI is:}$ $1. \text{ Easy to spray at high altitudes.}$ $2. \text{ Easy to synthesize.}$ $3. \text{ Having crystal structure similar to ice.}$ $4. \text{ Insoluble in water.}$

Options:

1. $\text{Easy to spray at high altitudes.}$
2. $\text{Easy to synthesize.}$
3. $\text{Having crystal structure similar to ice.}$
4. $\text{Insoluble in water.}$

Solution:

$\text{It is due to same crystal lattice as ice.}$ $\text{Due to similar structure, the adsorption becomes more effective and the neutralization of charge coagulates clouds to bring in rain.}$ $\text{The process is known as \"cloud seeding\".}$
