1L, 0 . 02M\left[Co{\left({NH}_{3}\right)}_{5}{SO}_{4}\right]Br is mixed with solution of \left[Co{\left({NH}_{3}\right)}_{5}Br\right]{SO}_{4} and treated with excess solution and solution respectively as shown below:
Solution \left(X\right) + {AgNO}_{3}\to Y1L solution (excess)
The number of moles of respectively are
Solution \left(X\right) + {AgNO}_{3}\to Y1L solution (excess)
The number of moles of respectively are
Options
- A
- B
- C
- D
Correct answer
B.
Step-by-step solution
The number of moles of
The number of moles of \left[Co{\left({NH}_{3}\right)}_{5}Br\right]{SO}_{4} = 0 . 02 \times 1 = 0 . 02mol\begin{cases}\left[Co{\left({NH}_{3}\right)}_{5}{SO}_{4}\right]Br & + & {AgNO}_{3} & \to & AgBr ↓ \\ 0 . 01mol & & excess & & 0 . 01mol\end{cases}\begin{cases}\left[Co{\left({NH}_{3}\right)}_{5}Br\right]{SO}_{4} & + & {BaCl}_{2} & \to & {BaSO}_{4} ↓ \\ 0 . 01mol & & excess & & 0 . 01mol\end{cases}$
