Definition and Usage Areas of Pure sodium hydroxide

Pure sodium hydroxide is a colorless, crystalline solid that melts at 318°C without decomposition. It is highly soluble in water, with a lower solubility in ethanol and methanol, but insoluble in ether and other non-polar solvents.

Similar to the hydration of sulfuric acid, dissolving solid sodium hydroxide into water is an extremely exothermic reaction in which a large amount of heat is released, posing a threat to safety with the possibility of splashing. The resulting solution is usually colorless and odorless. As with other alkaline solutions, it becomes slippery in contact with the skin.

Sodium hydroxide reacts with protic acids to produce water and associated salts. For example, when sodium hydroxide reacts with hydrochloric acid, sodium chloride is formed:

NaOH ( sulu ) + HCI (sulu) → NaCI (aq) + H 2 O ( l )

In general, such neutralization reactions are represented by a simple net ionic equation:

OH – (aq) + H + (sulu) → H 2 O (I)

This type of reaction with a strong acid dissipates heat and is therefore exothermic. These acid-based reactions can also be used for titrations. However, sodium hydroxide is not used as the primary standard because it is hygroscopic and absorbs carbon dioxide from the air.

Caustic Soda is a white hygroscopic substance. It dissolves easily in water and forms a soft, slippery and soapy solution. It has an itchy effect on human tissue. It is used in the laboratory to capture acidic gases such as CO2. It is used in the manufacture of many chemicals in industry, artificial silk, soap, paper, paint, detergent industry and oil refineries. When it reacts with water, its temperature rises to 50 degrees Celsius in about 5 minutes and remains hot for about 15 minutes.
