WebAll replies (13) Greenish Fe (OH) 2 begins to precipitate at pH=7.5 (from 0.01M solutions), and rust-colored Fe (OH) 3 begins to precipitate at pH=2 (from 0.01M solutions). Under … WebMinimum Fe solubility occurs between pH 7.5 and 8.5, which is the pH range of most calcareous soils (Lindsay, 1991). Increases in soil pH or Eh (oxidizing conditions) shift Fe from exchangeable and organic forms to water-soluble and Fe oxide forms.
