Solubility Data: KNO3
Aqueous solubility of inorganic salts, sugars, and organic compounds vs temperature (0–100°C). Used in crystallization design, mass transfer calculations, precipitation reactions, and environmental chemistry. Values in g per 100 g water.
| solute | temperature C | crystal form | heat of solution kJ per mol (kJ/mol) | solubility g per 100g solvent (g/100g) | solubility mol per L (mol/L) | solubility ppm (ppm) | solute type | solvent | temperature coefficient g per 100g per C (g/100g/C) |
