K ₂ [ Hgl ₄ ] detects the following ion

Options

  1. ACl ⁻
  2. BNO ₂⁻
  3. CNO ₃⁻
  4. DNH ₄⁺

Correct answer

D. NH ₄⁺

Step-by-step solution

Analysis of NH ₄⁺ cation Take small amount of salt in the test tube and add NaOH and heat. Add Nessler's reagent [ K ₂ H ₃ I ₄ ] to the solution, brown ppt is obtained. It confirmed NH ₄⁺ ion.
