Column-I | Column-II | ||
(a) | Cu + dil HNO3 | (p) | NO |
(b) | Cu + conc HNO3 | (q) | NO2 |
(c) | Zn + dil HNO3 | (r) | N2O |
(d) | Zn + conc HNO3 | (s) | Cu(NO3)2 |
(t) | Zn(NO3)2 |
Text Solution
Verified by ExpertsThe correct answer is:
A
A → p, s ; B → q, s ; C → r, t ; D → q, t
Sol. 3Cu + 8HNO 3 (dilute) ⎯→ 2NO + Cu(NO 3 ) 2 + 4H 2 O
Cu + 4HNO 3 (concentrated) ⎯→ 2NO 2 + Cu(NO 3 ) 2 + 2H 2 O
4Zn + 10HNO 3 (dilute) ⎯→ 4Zn(NO 3 ) 2 + N 2 O + 5H 2 O
Zn + 4HNO 3 (concentrated) ⎯→ Zn(NO 3 ) 2 + 2NO 2 + 2H 2 O
