Corrosion inhibitors are chemical substances that, when added in small concentrations, stop or reduce the corrosion or reaction of the metal with the environment. It normally functions by one or more of the following mechanisms:
(i) It may alter the external environmental conditions by taking away or inactivating an aggressive agent;
(ii) It may adhere to form a film on the surface of the metal;
(iii) It brings about the formation of corrosion products.
This question is taken from book named – A Self Learning Manual – Mastering Different Fields of Civil Engineering Works (VC-Q-A-Method) by Vincent T. H. CHU.
