(Note, this is a different form of iron oxide to that used in
Worked example 5.10, hence a different value for K).
Derive the relationship between the concentration of Fe
31
ions in solution and pH.
Use this equation to plot the concentration of Fe
31
over the
pH range 1-9.
How well does this information agree with the Fe
31
concen-
trations calculated in Question 4?
(ix) What properties of a soil would you investigate in order to learn
about its ability to hold and supply P and K to crops?
(x) What properties of soil would you investigate in order to learn
about the ability of a soil to act as a sink for pollutants?
