The micronutrient iron is abundant in soil,but often unavailable to plants due to insolubility.Knowing that the reaction Fe(OH)₃ + 3 H⁺ ↔ Fe³⁺ + 3 H₂O occurs,and assuming all soil samples have same total amount of iron in them,which type of soil would you predict to have the highest amount of soluble iron?

Question

Quizplus · Accepted Answer

In acidic soils, the concentration of H⁺ ions is higher, which shifts the equilibrium of the reaction to the right, increasing the concentration of soluble Fe³⁺ ions.
