Potassium Nitrate
Apr 06, 2018

Potassium nitrate is the potassium nitrate, experimental formula KNO3 (potassium nitrate is an ionic compound, there is no molecule, so there is no molecular weight, only the amount). The appearance is transparent and colorless or white powder, odorless, specific gravity (water=1) is 2.11. The solubility in water is 13 g/100 mL (depending on the temperature, the higher the temperature, the higher the solubility, among chemicals, the change of potassium nitrate solubility is quite obvious). The deliquescence is lower than that of sodium nitrate, which cools and stimulates the taste of salt. Soluble in water, slightly soluble in ethanol.
