A chloride salt solution acidified with dil. HNO3{HNO}_{3} gives a curdy white precipitate, [A][ A ], on addition of AgNO3{AgNO}_{3}. [A] on treatment with NH4OH{NH}_{4}OH gives a clear solution, B.A chloride salt solution acidified with dil. HNO _ 3 gives a curdy white precipitate, [ A ] , on addition of AgNO _ 3 .

Options

  1. AH[AgCl3] and [Ag(NH3)2]ClH\left[{AgCl}_{3}\right] \text{ and } \left[Ag{\left({NH}_{3}\right)}_{2}\right]Cl
  2. BH[AgCl3] and (NH4)[Ag(OH)2]H\left[{AgCl}_{3}\right] \text{ and } \left({NH}_{4}\right)\left[Ag ( OH{)}_{2}\right]
  3. CAgCl and [Ag(NH3)2]ClAgCl \text{ and } \left[Ag{\left({NH}_{3}\right)}_{2}\right]Cl
  4. DAgCl and (NH4)[Ag(OH)2]AgCl \text{ and } \left({NH}_{4}\right)\left[Ag ( OH{)}_{2}\right]

Correct answer

C. AgCl and [Ag(NH3)2]ClAgCl \text{ and } \left[Ag{\left({NH}_{3}\right)}_{2}\right]Cl

Step-by-step solution

Salt solution acidified with dilute HNO3{HNO}_{3} on addition of silver nitrate gives a curdy white precipitate soluble in ammonium hydroxide solution. This indicates the presence of Cl−{Cl}^{-} ions in the salt.

A chloride salt solution acidified with dil. HNO _ 3 gives a curdy white precipitate, [ A ] , on addition of AgNO _ 3 .
