Match List-I with List-II concerning the preliminary tests of anions using dilute .
Choose the correct answer from the options given below:
| List-I (Anion) | List-II (Observation) |
|---|---|
| (A) Carbonate () | (I) Reddish-brown gas |
| (B) Sulphide () | (II) Suffocating smell of burning sulphur |
| (C) Sulphite () | (III) Brisk effervescence |
| (D) Nitrite () | (IV) Rotten egg smell |
Choose the correct answer from the options given below:
Options
- A(A)-(III), (B)-(II), (C)-(IV), (D)-(I)
- B(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
- C(A)-(I), (B)-(IV), (C)-(II), (D)-(III)
- D(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
Correct answer
B. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Step-by-step solution
When treated with dilute :
Carbonate () gives gas which produces brisk effervescence.
Sulphide () gives gas which has a characteristic rotten egg smell.
Sulphite () gives gas which has a suffocating smell of burning sulphur.
Nitrite () gives gas which is a reddish-brown gas.
Therefore, the correct match is (A)-(III), (B)-(IV), (C)-(II), (D)-(I).
Answer: (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Carbonate () gives gas which produces brisk effervescence.
Sulphide () gives gas which has a characteristic rotten egg smell.
Sulphite () gives gas which has a suffocating smell of burning sulphur.
Nitrite () gives gas which is a reddish-brown gas.
Therefore, the correct match is (A)-(III), (B)-(IV), (C)-(II), (D)-(I).
Answer: (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
