Definition

Adjective: 1. Containing water that is chemically combined with a substance: Specifically, this refers to a compound that has water molecules incorporated into its crystalline structure, known as water of crystallization or hydration water. This water is not merely mixed but is an integral part of the compound's solid form.

Usage

The adjective "hydrated" is primarily used in scientific contexts, particularly chemistry, geology, and materials science, to describe the state of a substance. It often contrasts with "anhydrous" (without water).

Examples

    • Gypsum is a hydrated form of calcium sulfate. (This means gypsum has water molecules in its crystal structure.)
    • The chemist analyzed the hydrated salt to determine its exact water content.

Advanced Usage
