10 Questions
What are the sources of reactants used in the Ostwald process?
Dry ammonia (free from moisture) produced in Haber’s process and dry air free from carbon dioxide
Which catalyst is used in the Ostwald process?
Platinum
What is the oxidising agent used in the Ostwald process?
Oxygen
What is the ratio of ammonia to air in the Ostwald process?
1:10
Why is quartz used in the Ostwald process?
Quartz is acid-resistant and helps in the absorption of nitrogen dioxide in water.
What is aqua fortis and why is it called so?
Nitric acid is called aqua Fortis because it is a colorless liquid that is highly corrosive, reacting with nearly all metals (except gold) and converting them to corresponding soluble nitrates.
What is aqua regia and how does it dissolve gold and platinum?
Aqua regia is a mixture of concentrated hydrochloric acid and nitric acid in a ratio of 3:1. It dissolves gold and platinum by evolving nascent chlorine which is highly reactive.
Define the fixation of nitrogen and explain its significance.
Fixation of nitrogen is the process of converting atmospheric nitrogen (N2) into useful nitrogenous compounds like ammonia. It is significant as it provides a vital source of nitrogen for plants and organisms.
How does thunderstorm rain water contain nitric acid and what reactions are involved?
During thunderstorms, nitrogen in the atmosphere reacts with oxygen to form nitric oxide when lightning discharges.
What is the molecular formula of nitric acid?
The molecular formula of nitric acid is HNO3.
