(A)+ tap water white turbidity soluble in a q . NH ₃(A) residue (B)+ NO ₂+ O ₂ Aqueous (A) gives brown ring on adding FeSO ₄ and Conc. H ₂ SO ₄ . Identify (A) .

Options

  1. ANaNO ₃
  2. BAgNO ₃
  3. CNaNO ₂
  4. DAgNO ₂

Correct answer

B. AgNO ₃

Step-by-step solution

(A)+ tap water white turbidity soluble in aq. NH ₃ . Tap water has Cl ⁻ and turbidity is soluble in aq NH ₃ . Turbidity is of AgCl and thus (A) has Ag ⁺ (A) also gives ring test of NO ₃⁻(A) has nitrate and thus (A) is AgNO ₃
