Question

What is the number of moles of silver chloride precipitated when excess of aqueous silver nitrate is treated with [Co(NH₃)₄Cl₂]Cl?

Options

• 4.0 mole

• 3.0 mole

• 1.0 mole

• 2.0 mole

Answer 1

1.0 mole

Explanation:

\[\ce{[Co(NH3)4Cl2]Cl ⇌ [Co(NH3)4Cl2]^+ + Cl^-}\]

Since only one Cl⁻ is in the ionization sphere only one mole of AgCl precipitated with an excess of AgNO₃.
