(C) | (R) give white ppt with solution |
(D) | (S) identified by brown ring test |
| (T) identified by methylene blue dye test |
Options:
Answer:
C
Solution:
1. S₂O₃²⁻ gives SO₂ gas with dilute H₂SO₄, so it matches (P).
2. NO₃⁻ is confirmed by the brown ring test, so it matches (S).
3. NO₂⁻ gives a violet precipitate with the Ni(en)₃(NO3)2 type complex test, so it matches (Q).
4. S²⁻ gives the methylene blue test, so it matches (T).
