Concept explainers
Interpretation:
Explain the relation between pH and corrosion of iron
Concept introduction:
Electro-chemical interaction of metal with the non-metals present in environment resulted in the deformation of the metal surface is called corrosion. Generally they are converted from metal state to oxide, hydroxide or sulfides respectively and found to be more stable than pure metal. In case of uncoated-steel, Fe act as anode and release two and undergoes oxidization to produce Fe2+. The half-cell reaction for corrosion can be written as follows.
Generally corrosion was accelerated by warm temperature, water and salts. In addition pH also has strong influence over corrosion.
To explain:
Influence of pH over the rusting of iron.
