It melts congruously at 7.55 °C into a liquid with 35.7% NaOH and density 1.392 g/cm 3, and therefore floats on it like ice on water. However, at about 4.9 °C it may instead melt incongruously into a mixture of solid NaOH·3.5H 2 O and a liquid solution.

The NaOH module calculates the physical properties of aqueous sodium hydroxide solutions in the temperature range from 20 °C to 100 °C and in the concentration range from 0 to 50 Ma-% NaOH. The following physical properties are calculated: Density. Specific heat capacity. Thermal conductivity.
14 Ιουλ 2023 · An inorganic compound with the chemical formula NaOH is sodium hydroxide, also known as lye and caustic soda. The substance in question is a solid ionic compound characterized by its white color. It comprises sodium cations (Na +) and hydroxide anions (OH –). Sodium hydroxide is classified as a solid ionic compound.
16 Νοε 2023 · Sodium hydroxide, which is a stronger base itself and forms from a more strongly basic oxide, melts at 323°C and boils at 1388°C — with no reported decomposition before boiling, at least from Wikipedia. Not surprisingly, the same result carries over to the heavier alkali hydroxides.
29 Ιουλ 2024 · This boiling point calculator tells you how to calculate the boiling point of most common substances at an arbitrary pressure, based on the Clausius–Clapeyron relation. Whether you want to analyze water, ethanol, or ammonia, simply provide some reference values, and this calculator will do the work for you.
