Deliquescent: meaning, definitions and examples

scientific term

Deliquescent refers to substances that absorb moisture from the atmosphere until they dissolve in the absorbed water. This characteristic is commonly observed in certain salts which can exist as solids but will transition into a liquid state upon attracting enough humidity from the air. This property is significant in various chemical and physical applications, such as understanding the behavior of hygroscopic materials. Deliquescent materials are often used in desiccators and humidity control applications.

hygroscopic, liquefying, moisture-absorbing.

Examples of usage

• Calcium chloride is a deliquescent substance that helps control humidity.

• Many deliquescent salts can cause corrosion if not handled properly.

• In humid environments, deliquescent substances may need special storage.

• Sodium hydroxide can be deliquescent, forming a liquid solution in high humidity.
