Definition and Areas of Use: :
Pure sodium hydroxide is a colorless, crystalline solid that melts at 318 °C without decomposition. Highly soluble in water, with a lower solubility in ethanol and methanol, but insoluble in ether and other nonpolar solvents.
Sülfürik asidin hidrasyonuna benzer şekilde, katı sodyum hidroksidin suya çözülmesi , büyük miktarda ısının serbest bırakıldığı aşırı derecede ekzotermik bir reaksiyondur [12] , bu da sıçrama olasılığına bağlı olarak emniyet için bir tehdit oluşturmaktadır. Elde edilen solüsyon genellikle renksiz ve kokusuzdur. Diğer alkalin solüsyonlarında olduğu gibi cilt ile temasında kayganlaşır.
Similar to the hydration of sulfuric acid, the dissolution of solid sodium hydroxide into water is an extremely exothermic reaction in which a large amount of heat is released [12], which poses a threat to safety due to the possibility of splashing. The resulting solution is generally colorless and odorless. As with other alkaline solutions, it becomes slippery in contact with the skin.
Sodium hydroxide is also known as kelp and caustic soda. Sodium hydroxide is a highly caustic base and alkali that can break down proteins at ordinary ambient temperatures and cause severe chemical burns.
Sodium hydroxide reacts with protic acids to produce water and related salts. For example, when sodium hydroxide reacts with hydrochloric acid, sodium chloride is formed:
NaOH (aq) + HCl (aq) → NaCl (aq) + H 2 O (l)
In general, such neutralization reactions are represented by a simple net ionic equation:
OH - (aq) + H + (aq) → H 2 O (I)
This type of reaction with a strong acid releases heat and is therefore exothermic. These acid-based reactions can also be used for titrations. However, sodium hydroxide is not used as a primary standard because it is hygroscopic and absorbs carbon dioxide from the air.
