On reaction of Lead Sulphide with dilute nitric acid which of the following is not formed ?
- Lead nitrate
- Sulphur
- Nitric oxide
- Nitrous oxide
The Correct Option is D
Solution and Explanation
To address this query, it is necessary to comprehend the chemical reaction between Lead Sulphide (PbS) and dilute nitric acid (HNO3).
The chemical reaction between lead sulphide and dilute nitric acid is depicted as follows:
\(PbS + 4HNO_3 \rightarrow Pb(NO_3)_2 + 2H_2O + 2NO_2 + S\)
An examination of the reaction reveals the formation of the subsequent products:
- Lead Nitrate (Pb(NO3)2)
- Sulphur (S)
- Nitrogen Dioxide (NO2)
- Water (H2O)
Evaluating the provided options leads to the following conclusions:
- Lead Nitrate: This compound is generated as a primary product during the reaction.
- Sulphur: This element is also produced, as indicated in the reaction equation.
- Nitric Oxide (NO): This compound is absent from the reaction, and thus, it is not formed.
- Nitrous Oxide (N2O): This compound is not mentioned in any aspect of the reaction and is not a typical byproduct when lead sulphide reacts with dilute nitric acid.
Based on this analysis, the definitive conclusion is:
Nitrous oxide (N2O) is not a product of this reaction.
