... Which of the following anions is most basic, which is least basic? CH3–, C4-, F–, I– The most basic ion is clearly C4-. Since methane is much less acidic than either HF or HI, its conjugate base must necessarily be more basic. Obviously further deprotonation of methane to give the methide anion prod ...

... d. Amphoteric means the molecule or ion may act as either an acid (H1+ donor) or a base (H1+ acceptor), depending on what other molecules are present in the solution. HOH is the most obvious example, but many ions like HCO31– and H2PO41– are amphoteric. e. Hydronium ion is H3O1+, the ion formed when ...
