WebThe equilibrium equation of solid KNO3 in water is represented as follows: KNO3 (s) = K+ (aq) + NO3 (aq) egn. 3 The solubility product constant Ksp is given as follows: Ksp = [K] [NO3] egn. 4 1 Thermodynamics of KNO: where [K] is the molar concentration of potassium ion and [NO3 ] is the molar concentration of NO3 for a saturated solution of KNO3. 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). Sodium nitrate is isomorphous with calcite, the most stable form of calcium carbonate, whereas room-temperature potassium nitrate is isomorphous with aragonite, a slightly less stable polymor…
