16 1 point When Fe(NO$_3$)$_3$ is dissolved in water, the dissociated Fe$^{3+}$ ion forms a complex with six water molecules in the form of Fe(H$_2$O)$_6^{3+}$. Fe(H$_2$O)$_6^{3+}$ acts as a Bronsted acid through the following reaction with water, Fe(H$_2$O)$_6^{3+}$(aq) + H$_2$O(l) $ ightleftharpoons$ Fe(H$_2$O)$_5$(OH)$^{2+}$(aq) + H$_3$O$^+$ (aq) Calculate the pH of a 0.10 M solution of Fe(H$_2$O)$_6^{3+}$ which has a K$_a$ of 6.0x10$^{-3}$ 1.23 1.66 2.05 2.33
