- noun a chemical reaction in which a substance reacts with water, causing decomposition of both the original substance and the water and the production of two or more other compounds
- A chemical reaction in which water reacts with another substance, and in which the latter is broken into two or more constituents. For example, sodium chloride (NaCl) dissolving in water to produce Na+ and Cl- ions.
- The reaction of water molecules with other compounds, usually to break them down into smaller subunits and requiring the action of acids, enzymes or long heating. It is used e.g. to convert starch into simpler sugars and is the process which occurs when starch solutions and sauces are thinned by boiling them too long.
- noun the breaking down of a chemical compound when it reacts with water to produce two or more different compounds, as in the conversion of starch to glucose
- noun a chemical reaction in which a compound reacts with water, causing decomposition and the production of two or more other compounds, e.g. in the conversion of starch to glucose
