At 90 degrees Celsius, potassium nitrate (KNO₃) is one of the most soluble salts in water. Its solubility increases significantly with temperature, reaching about 62 grams per 100 milliliters of water at this temperature. Other highly soluble salts at elevated temperatures include sodium nitrate (NaNO₃) and calcium chloride (CaCl₂), but potassium nitrate is particularly notable for its high solubility.
