  2. Cloud seeding - Wikipedia

    en.wikipedia.org/wiki/Cloud_seeding

    Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation, mitigate hail or disperse fog. The usual objective is to increase rain or snow, either for its own sake or to prevent precipitation from occurring in days afterward.

  3. Sodium nitrate - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrate

    Sodium nitrate is the chemical compound with the formula Na N O 3.This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate.

  4. Anti-fog - Wikipedia

    en.wikipedia.org/wiki/Anti-fog

    Anti-fog agents, also known as anti-fogging agents and treatments, are chemicals that prevent the condensation of water in the form of small droplets on a surface which resemble fog. They are one of many additives used in the production of plastics.

  5. Sodium nitrite - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrite

    Above 330 °C sodium nitrite decomposes (in air) to sodium oxide, nitric oxide and nitrogen dioxide. [88] 2 NaNO 2 → Na 2 O + NO + NO 2. Sodium nitrite can also be used in the production of nitrous acid: 2 NaNO 2 + H 2 SO 4 → 2 HNO 2 + Na 2 SO 4. The nitrous acid then, under normal conditions, decomposes: 2 HNO 2 → NO 2 + NO + H 2 O

  7. Condensed aerosol fire suppression - Wikipedia

    en.wikipedia.org/wiki/Condensed_aerosol_fire...

    Some aerosol-generating compounds (e.g., potassium nitrate-based) produce a corrosive by-product that may damage electronic equipment, although later generations lower the effect. Condensed aerosol fire suppression systems employ a fire-extinguishing agent consisting of very finely divided solid particles, suspended in an inert gas.

    At the other extreme, cesium nitrate melts at 414 °C (777 °F) and decomposes at 584 °C. [2] 60:40 mixture of sodium nitrate and potassium nitrate is a liquid between 260–550 °C (500–1,022 °F). It has a heat of fusion of 161 J/g, [3] and a heat capacity of 1.53 J/(g·K). [4]

  9. Hummers' method - Wikipedia

    en.wikipedia.org/wiki/Hummers'_Method

    Hummers' method is a chemical process that can be used to generate graphite oxide through the addition of potassium permanganate to a solution of graphite, sodium nitrate, and sulfuric acid. It is commonly used by engineering and lab technicians as a reliable method of producing quantities of graphite oxide.
