Question

presence of oxides of nitrogen, sulphur and carbon enhance the process of rusting of iron.

Answer 1

Answer:

Do you know Delhi is one of the most polluted cities in the world? The presence of toxic gasses and various air pollutants usually cross the permissible limit. Central Pollution Control Board suggests that the air quality of Delhi is in extremely poor condition and it is breaching all the permissible air quality standards. Oxides of sulphur and nitrogen, oxides of carbon, hydrocarbons, hydrogen sulphide, ozone and other oxidants gaseous along with particulate pollutants like fumes, dust, smoke, etc. are the air pollutants that are responsible for severe air pollution in Delhi as well as many other states in India.

Answer 2

Oxides of nitrogen Sulphur and carbon results in the emission of oxygen when present on the surface of iron.  oxygen can now react with iron in the presence of moisture. Hence rusting is enhanced

Explanation:

• certain metal surface reacts with oxygen and moisture which is present in the air and gets coated with it by the formation of iron oxide in case of iron.

• This process is known as rusting of the iron. This reduces the tensile strength of the iron and also causes destruction of the iron. For this purpose there are a large number of processes which are used to prevent rusting.

• One of the process is the galvanizing on the iron. Painting is one of the cheapest method to prevent rusting of the metal.
