Question

$0.02$ mole of $[Co(NH_{3})_{5}Br]Cl_{2}$ and $0.02$ mole of $[Co(NH_{3})_{5}Cl]SO_{4}$ are present in $200\, cc$ of a solution $X$. The number of moles of the precipitates $Y$ and $Z$ that are formed when the solution $X$ is treated with excess silver nitrate and excess barium chloride are respectively

• A. 0.02, 0.02
• B. 0.01, 0.02
• C. 0.02, 0.04
• D. 0.04, 0.02

Answer 1

Answer: (D)

0.04, 0.02

Answer 2

$\underset{1 mol}{[ Co \left( NH _{3}\right)_{5} Br ]} Cl _{2}+2 AgNO _{3} \longrightarrow$

$\underset{1 mol}{[Co(NH_{3})_{5}Cl]}SO_{4}+BaCl_{2} \to$
