Question
Complete the table given below:
| Name of the process | Reactants | Acid product formed |
| (a) ______ | Nitrogen dioxide + water + oxygen | (b) ______ |
| (c) ______ | Oleum + water | Sulphuric acid |
Solution
| Name of the process | Reactants | Acid product formed |
| (a) Fixation of atmospheric nitrogen | Nitrogen dioxide + water + oxygen | (b) Nitric acid |
| (c) Contact process | Oleum + water | Sulphuric acid |
Explanation:
(a) The reaction of nitrogen dioxide with water and oxygen is the last step of the preparation of nitric acid from atmospheric nitrogen gas. The conversion of free atmospheric nitrogen into useful nitrogenous compounds in the soil is called the fixation of atmospheric nitrogen.
(b) The reaction of nitrogen dioxide with water and oxygen gives nitric acid. The reaction is given as:
\[\ce{4NO2 + 2H2O + O2 -> 4HNO3}\]
(c) Contact process is the process used for the manufacturing of sulphuric acid at an industrial scale. The given reaction is the last step of the contact process in which oleum is diluted to give sulphuric acid.
