Anhydrous (adjective): Without water; free from water molecules or moisture.
From Greek an-, meaning "without," and hydros, meaning "water."
Importance: Critical for reactions where water would interfere or cause unwanted side reactions.
Storage: Must be kept in sealed containers with desiccants to prevent water absorption.
Examples: Anhydrous magnesium sulfate (MgSO₄), anhydrous sodium carbonate (Na₂CO₃).
Electronics: Prevents corrosion and short circuits in sensitive equipment.
Manufacturing: Essential in processes where water contamination affects product quality.
Quality Control: Strict moisture limits ensure consistent product performance.
Organometallic Chemistry: Many metal compounds react violently with water.
Preparation: Dried using molecular sieves, distillation, or chemical drying agents.
Storage: Kept under inert atmosphere (nitrogen or argon) to prevent water uptake.
Concentration: Contains 82% nitrogen, higher than other nitrogen fertilizers.
Application: Injected directly into soil where it dissolves in soil moisture.
Handling: Requires special equipment due to its corrosive and toxic properties.
