Answer:
The correct equation will be "[Fe(H2O)5]²⁺ + NO → Fe(H2O)5NO]²+ (brown ring)
".
Explanation:
For NO₂, the addition of H₂SO₄ forms HNO₂ comprising NO gas as well as HNO₂, the equation will be:
⇒ NO₂⁻ + 2H⁺ → HNO2
⇒ HNO₂ + H₂O + H⁺ → HNO₃ + NO
For NO₃⁻,
NO₃⁻, Fe₂+ oxidized to Fe₃ + then releases NO gas in the existence of H₂SO₄
⇒ 3Fe₂⁺ + 4H⁺ + NO₃⁻ → 3Fe₃⁺ + NO + 2H₂O
Brown ring forming establishes NO3- presence in the initial test sample,
⇒ [Fe(H2O)5]²⁺ + NO → Fe(H2O)5NO]²+ (brown ring)
The amount remaining is obtained using the half life data. The total amount remaining after one hour is equal to 1/( e^ (ln2/(20/60))*1). The final answer is 0.125 grams.
