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.
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.
14 Ιουλ 2023 · At a temperature of 20 °C, the solubility of sodium hydroxide (NaOH) in water is 109 grams per 100 grams of water. Additionally, the heat of solution for this process is -44.5 kJ mol -1 (kilojoules per mole).
Caustic Soda Solution 50% fulfils the criteria of purity for food additives according to Zusatzstoff- Zulassungsverordnung (ZZulV), Zusatzstoff- Verkehrsverordnung (ZVerkV), Food Chemicals Codex (FCC) and of products for water treatment concerning to human applications referred to DIN EN 896.
The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to the surrounding atmospheric pressure, thus facilitating transition of the material between gaseous and liquid phases.
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. Dynamic viscosity. Kinematic viscosity. Prandtl number.
