1.	Which of the following is an example of adsorption-type inhibitors?(a) Arsenic(b) Sodium sulfite(c) Organic amines(d) ChromatesI had been asked this question by my school teacher while I was bunking the class.Query is from Corrosion Prevention topic in section Corrosion Prevention of Corrosion Engineering
Answer» Correct choice is (c) Organic amines To explain I WOULD say: Adsorption-type inhibitors are the type of inhibitors that ADSORB on the surface of CATHODE or ANODE and alter its surface. Organic amines are examples of adsorption-type inhibitors.
