Answers
Answerwasdown
Explanation:
Explanation:
Nitrogen gas can be prepared using the following compounds: (a) NH4Cl and (b) CaOCl2.
To prepare nitrogen gas using (a) NH4Cl, the following steps can be taken:
Mix a small amount of NH4Cl with concentrated sulfuric acid (H2SO4).
Heat the mixture until white fumes of nitrogen gas and hydrogen chloride gas are evolved.
Collect the nitrogen gas by downward delivery.
To prepare nitrogen gas using (b) CaOCl2, the following steps can be taken:
Take a mixture of CaOCl2 and water in a flask.
Heat the mixture until white fumes of nitrogen gas are evolved.
Collect the nitrogen gas by downward delivery.
In both the methods, nitrogen gas is obtained as a byproduct. The reaction between the compounds and the strong acid or strong base leads to the formation of nitrogen gas and other gases. The collected nitrogen gas can be tested for its purity using physical and chemical tests.
In conclusion, nitrogen gas can be prepared using (a) NH4Cl and (b) CaOCl2 by reaction with a strong acid or strong base. The purity of the collected nitrogen gas can be tested using physical and chemical tests.
