WebNaOH is miscible with water at all proportions but solidifies at 20°C if the concentration is higher than 52% (by weight), which can be considered the maximum water solubility at 20°C. NaOH has a very low vapour pressure (< 10-5 hPa at 25°C). The octanol water partition coefficient is not relevant for an inorganic substance such as NaOH. flags in worship
