Element not present in Nessler’s reagent is

Options

  1. AN
  2. BHg
  3. CI
  4. DK

Correct answer

A. N

Step-by-step solution

Nessler's reagent is an aqueous solution of potassium iodide, mercuric chloride, and potassium hydroxide. Its chemical formula is K 2 HgI 4 . It is used to detect the presence of ammonia. It turns into pale brown colour in presence of ammonia. So, N is not present in Nessler's reagent.
