Chapter 12, Problem 12.8P

Interpretation Introduction

Interpretation:

Reason behind reduced solubility of basic anion with decrease in $\text{pH}$ has to be given and equation that describes mobilization of trace elements with rainwater should be written along with reason of increased solubility of kaolinite and bauxite in acidic media.

Concept Introduction:

Le-Chatelier’s principle suggests if any change in reaction condition occurs, the equilibrium is favored in opposite direction so as to undo the effect. For instance, if concentration of products is increased then reaction tends to shift in direction of substrates.
