A chloride salt solution acidified with dil. HNO 3 gives a curdy white precipitate, [ A ] , on addition of AgNO 3 . [A] on treatment with NH 4 OH gives a clear solution, B.

Options

  1. AH AgCl 3 & Ag NH 3 2 Cl
  2. BH AgCl 3   &   NH 4 Ag ( OH ) 2
  3. CAgCl   &   Ag NH 3 2 Cl
  4. DAgCl   &   NH 4 Ag ( OH ) 2

Correct answer

C. AgCl   &   Ag NH 3 2 Cl

Step-by-step solution

Salt solution acidified with dilute HNO 3 on addition of silver nitrate gives a curdy white precipitate soluble in ammonium hydroxide solution. This indicates the presence of Cl - ions in the salt.
