Assertion (A): Brown fumes are produced when lead nitrate is heated. (1) Reason(R): Nitrogen dioxide gas is produced as a by- product due to the decomposition of lead nitrate. |

Answer» Answer: Both A and R are true and R is the correct explanation of A.
Explanation: Required Answer: Asertion Brown fumes are produced when LEAD nitrate is hated - The assertion is true because when lead nitrate is decomposed by heating, we get lead OXIDE (YELLOW), nitrogen DIOXIDE (brown fumes) and oxygen gas.
Reason : Nitrogen dioxide gas is produced as a byproduct due to the decomposition of lead nitrate. - The reason is also true because nitrogen dioxide gas is RELEASED as represented above in the reaction. They are brown in colour and are released as fumes. Hence:- Assertion and Reason both are true and Reason is the correct explanation of Assertion because it is describing about why brown fumes are produced. Therefore∴ Option A is the correct option. |
