Exothermic ionic bonds
WebThis is accomplished by replacing each ionic bond with multiple solvent-solute interactions. This step in the solvation process involves the breaking of a strong bond by multiple weak interactions with the solvent and as a result is heat-releasing, or an exothermic reaction. For example, consider the dissolution of sodium hydroxide, NaOH, in water. WebJan 19, 2012 · Brimley.
