Compounds with this property are commonly used in buffers for their stability across pH ranges.
A class of surfactants named for possessing this property experience a minimum solubility in the pH range of 7 to 8 due to the phenomenon of "tail-biting". A common antifungal drug named for its possession of this property binds to ergosterol to cause a rapid leakage of monovalent ions. One lead-based compound with this property exists in two polymorphs called massicot and litharge. Another compound that possesses this property is dissolved in cryolite in one step of the (*) Hall-Heroult process. Many metalloid oxides typically exhibit this property, and other common compounds with this property include ammonia and water. Compounds with this property are commonly used in buffers for their stability across pH ranges. For 10 points, name this property describing compounds that both donate and accept electron pairs when in solution.
