Question

Name a nitrate which produces brown gas on heating.

Answer 1

Hint: In the given question we have to find out what products or products would form on the conduction of given reaction. Now we know that the nitrate would need to emit a product which is both gas and brown in colour when it is heated under the optimal conditions. This is the lead nitrate that would fulfill both these demands simultaneously.

Complete Step by step Solution:
The given question is asked about the product that would form when the given process will take place, which is the production of a brown colour gas on heating. This process is a somewhat practical representation of the gradual process under the ideal condition.
Now for the given reaction of a nitrate we must know what a nitrate is. The nitrate of any element refers to the compound where the polyatomic ion with the chemical formula \[N{O_3}^ - \] is attached to it through the chemical bonding process mostly ionic or covalent. Whereas the salts which are containing this type of anion are basically what is called nitrates. Nitrates are common components of fertilizers and explosives.
And for the given question the answer is, Lead nitrate is the desired nitrate that produces the brown gas in the process of heating. It has the crystal structure that has been determined by neutron diffraction.
Now we have to do step by step solution of the reaction and then we can get the answer:

Note: Lead(II) nitrate is an inorganic compound with the chemical formula \[Pb{(N{O_3})_2}\].It commonly occurs as a colourless crystal or white powder and, unlike most other lead(II) salts, is soluble in water. Known since the Middle Ages by the name plumbum dulce, the production of lead(II) nitrate from either metallic lead or lead oxide in nitric acid was small-scale
