Reactive Group Datasheet

Water and Aqueous Solutions

Water is nonflammable.
Water reacts with many substances, including but not limited to alkali metals, hydrides, strong halogenating agents, and chlorosilanes. These reactions can be hazardous and may result in flammable or toxic gas production, or generation of excessive heat that may cause pressurization to occur. Another reactive hazard is heat of mixing. Mixing substances such as sulfuric acid or sodium hydroxide with water may generate significant heat. Additionally, water is a good solvent for polar molecules, so it can form aqueous solutions if it comes into contact with such molecules.
Water itself is nontoxic and is in fact essential for life. Solutes dissolved in water may be toxic, but those interactions are covered by the reactive groups that the solute belongs to.
Other Characteristics
This reactive group is used to account for the water component of aqueous solutions or solids containing some water (for example, nitroexplosives wetted with water to desensitize), as well as adding water itself to a mixture.
