Research concerning miscibility often involves the materials science chemistry domain where additional strategies to predict substance interactions could ... WitrynaA. Classification of Solvents There are three broad solvent categories, and they are not mutually exclusive; that is, a solvent can be in more than one category. 1. A solvent can be protic or aprotic. 2. A solvent can be polar or apolar. 3. A solvent can be a donor or a nondonor. A protic solvent consists of molecules that can act as hydrogen ... fuller field wethersfield ct
