What quantity of AgCl is precipitated when one mole of Pentaamminecarbonatocobalt(III) chloride is treated with excess AgNO ₃ (molar mass = 143.3 g mol ⁻¹ ) solution?

Step-by-step solution

The formula of pentaamminecarbonatocobalt(III) chloride is [ Co ( NH ₃)₅( CO ₃)] Cl . In this complex, there is one ionizable chloride ion present outside the coordination sphere. When one mole of this complex is treated with excess AgNO ₃ solution, it yields one mole of AgCl precipitate. [ Co ( NH ₃)₅( CO ₃)] Cl + AgNO ₃ [ Co ( NH ₃)₅( CO ₃)] NO ₃ + AgCl Mass of one mole of AgCl = 143.3 g . Therefore, 143.3 g of AgCl is precipitated. Answer: 143.3 g
