Calcium hydroxide, known commonly as slaked lime, is a versatile compound with distinct physical and chemical properties that dictate its use and handling. It typically presents as a white, odorless powder. Chemically, it is a strong base, indicated by its high pH when dissolved in water, forming a solution known as limewater. While only sparingly soluble in water, this solution is potent enough to neutralize acids effectively. It's important to note that calcium hydroxide can decompose at high temperatures, around 580°C.

When handling calcium hydroxide, safety is a primary concern. As a strong alkali, it can cause irritation to the skin and eyes upon contact. Therefore, it is crucial to use appropriate personal protective equipment (PPE), including gloves, safety goggles, and respiratory protection if dust is present. Proper storage is also vital; calcium hydroxide should be kept in a cool, dry, well-ventilated area, away from incompatible materials such as acids and certain oxidizing agents. Airtight containers are recommended to prevent it from absorbing moisture and carbon dioxide from the atmosphere, which can degrade its quality. For those involved in chemical manufacturing basics or any application requiring calcium hydroxide, understanding these properties and adhering to safety guidelines is essential.
