When a dilute AgNO ₃ solution is mixed with excess of dilute KI , the colloidal solution formed is

Options

  1. AAgNO ₃ / I ⁻
  2. BAgl
  3. CAgl / Ag ⁺
  4. DAgl / I ⁻

Correct answer

D. Agl / I ⁻

Step-by-step solution

When dilute aqueous solution of AgNO ₃ is added to dilute solution of KI (excess) a negatively charged sol of AgI is formed due to the preferential adsorption of I ⁻ ions from the dispersion medium.
