Which chemical is used for cloud seeding?
Most cloud seeding operations, including those run by DRI, use a compound called silver iodide (AgI) to aid in the formation of ice crystals. Silver iodide exists naturally in the environment at low concentrations, and is not known to be harmful to humans or wildlife.
Which salt is used for artificial rain?
Devised in the late 1940s, cloud seeding is defined as an intentional treatment of clouds to enhance rainfall. When aerially sprayed (with the help of aircraft, and at times rockets), certain chemicals such as sodium chloride (common salt) and silver iodide (another non-toxic chemical) can augment rainfall.
Is silver nitrate used for artificial rain?
Silver iodide is used for producing artificial rains because when $AgI$ is sprayed over clouds it causes water droplets of clouds to coalesce to form bigger water drops and induce rains.
What is artificial rain technology?
3 Artificial Rain Technology Artificial rain is rainfall that made by human intervention with making rain through cloud seeding or laser pulse. … The most common chemicals used for cloud seeding include silver iodide and dry ice (solid carbon dioxide). Liquid propane which expands into a gas has also been used.
Why is potassium iodide used in cloud seeding?
What is cloud seeding? … The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide) and Liquid propane. These salt particles act as a core (cloud condensation nuclei or ice-nucleating particles) which draw water vapour within the cloud towards them.
