What is Sodium Hydroxide’s Physical Properties?

When somebody tends to talk about the question “What is sodium hydroxide,” it is impossible to overlook the substance’s physical characteristics. Sodium hydroxide demonstrates many physical traits. It appears as white, hard, and opaque crystals when it is pure. Surprisingly, it possesses no smell. The density of sodium hydroxide is 2.13 g/cm3, so it is relatively dense in its solid state. It is a solid at room temperature because sodium hydroxide melting point is 323 °C, which is considered high.

The sodium hydroxide boiling point is high, too, rising to 1,388 °C before turning into a gas. Its solubility in water changes with temperature, rising significantly to 3370 g/L at 100 °C from 418 g/L at 0 °C and 1000 g/L at 25 °C. Sodium hydroxide molar mass is counted as 39.9971 g/mol.

Additionally, the substance has limited solubility in ammonia, is insoluble in ether, dissolves slowly in propylene glycol, and is soluble in glycerol. It also exhibits solubility in methanol, where it dissolves at a rate of 238 g/L, and in ethanol, where it dissolves at a rate of less than 139 g/L. At 20 °C, its vapor pressure is only 2.4 kPa, which is quite low. Furthermore, its refractive index (nD) is 1.3576.


What are Sodium Hydroxide’s Production Process?

The sodium hydroxide manufacturing process is critical in shaping its chemical and physical properties, such as the molar mass of sodium hydroxide, ultimately determining its wide variety of applications. Utilizing sodium hydroxide’s adaptability across various industries, from chemical processes to water treatment, requires an understanding of these manufacturing methods and the intricate processes involved.

The First Method

The chlor-alkali process is one of the most common ways to make this crucial substance. This process involves passing a direct electric current through a sodium chloride brine to electrolyze it. As a result of this procedure, sodium ions, and hydrogen gas amass at the cathode, while chloride ions are transformed into elemental chlorine at the anode.
