How can I calculate solubility of potassium nitrate?
Jul 28, 2014 · The only way to determine the solubility of potassium nitrate is to do an experiment or interpolate from a solubility graph. Solubility is the mass of a solute that can be dissolved in a given mass of solvent.
Potassium nitrate - Wikipedia
Potassium nitrate has an orthorhombic crystal structure at room temperature, which transforms to a trigonal system at 128 °C (262 °F). On cooling from 200 °C (392 °F), another trigonal phase forms between 124 °C (255 °F) and 100 °C (212 °F).
