For 10 points—what term describes a molecule or ion capable of either accepting or donating a proton?
Examples of this type of chemical species include the ions HSO41- [H-S-O-4, 1 minus], H2PO41-, and water itself; their behavior is governed both by the presence of other species, and the pH of the solution. In all cases, they must have at least one proton. For 10 points—what term describes a molecule or ion capable of either accepting or donating a proton?
