B(only reacts with water, and Fe(OH)3 is neutral; B is correct. The Fe3+ (aq) has water molecules acting as Lewis bases and that coordinate to the Fe3+ ion. The ion is electron withdrawing and makes the polar covalent bond of these coordinated water molecules, even more polarized, resulting in dissociation of hydrogen ions and producing iron (III) hydroxide as the “orange gelatinous precipitate.” This precipitate is consistent with the observations observed in Table 1, when the iron (III) nitrate solution is combined with the sodium hydroxide solution.)
