Abstract: | Summary The solubility of two manganese oxides was measured in 5×10–5 to 15×10–5
M iron and organic acid solutions. The oxides were soluble in all the 15 × 10–5
M solutions tested except ferric chloride. The amount of manganese dissolved by mixtures of the iron and acid solutions was greater than the sum of that dissolved by the separate solutions. It was suggested that ferric chloride should be used as the iron source in critical studies of the availability of manganese oxides in sand cultures. |
