Potassium nitrate has an orthorhombic crystal structure at room temperature, which transforms to a trigonal system at 129 °C (264 °F). Hydroponic grade potassium nitrate fertilizer. - 1 - Solubility Curve of Potassium Nitrate in Water Introduction Background Solutions are homogeneous mixtures of solvents (the larger volume of the mixture) and solutes (the smaller volume of the mixture). (a) Potassium nitrate will begin to crystallise at about 56 °C, when its solubility is 100 g/100g water. For example, a hot chocolate is a solution, in which the solute (the chocolate powder) is dissolved in the solvent (the milk or water).
