When sodium argentocyanide is treated with zinc dust, silver precipitates because

Options

  1. ABoth Zn ⁺² and Ag ⁺ ions have d ¹⁰ electronic configuration
  2. BZinc forms a complex readily with cyanide
  3. CZinc is more electropositive than silver
  4. DZinc is less electropositive than silver

Correct answer

C. Zinc is more electropositive than silver

Step-by-step solution

Zinc is more electropositive than silver therefore, it displaces less electropositive silver.
