Measuring the pH of a solution of iron (III) hexahydrate. Iron (III) chloride is dissolved in the water. The ferric ions are quickly hydrated, forming the metal complex ion ferric hexahydrate (Fe(H2O)6)3+. This ion is acidic, donating a proton to the water molecules in solution, forming hydronium ions, which lowers the pH of the solution. | |
