Properties of Sodium Hydroxide – NaOH. Sodium Hydroxide is a white, translucent crystalline solid. It is commonly referred to as caustic soda due to its corrosive action on many substances; it decomposes proteins at room temperatures and may cause chemical burns to human bodies.
Properties. Physical properties. Pure sodium hydroxide is a colorless crystalline solid that melts at 318 °C (604 °F) without decomposition and boils at 1,388 °C (2,530 °F). It is highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol. [14] .
Sodium hydroxide is commercially produced as a 50% solution by the electrolysis of brine, a solution of sodium chloride (NaCl) in water, using the chloralkali process. This process also yields chlorine gas and hydrogen gas.
Sodium hydroxide is the most used base in chemical laboratories. Pure sodium hydroxide is a white solid; available in pellets, flakes, granules and as a 50% saturated solution. It is deliquescent and readily absorbs carbon dioxide from the air, so it should be stored in an airtight container.
23 Μαρ 2024 · 1.1. Physical Properties of Sodium Hydroxide. Some physical properties of solid sodium hydroxide are as follows: molar mass of sodium hydroxide is 40 g/mol. Appearance: white, crystalline. Density of sodium hydroxide (liquid, 350 °C)= 1.77 g/cm3. mp (soda and water free) 322 ± 2 °C. 1.2. Chemical Reactions of sodium hydroxide.
