Question

Consider a mixture ‘X’ which is made by dissolving 0.4 mol of $[Co {({NH}_{3})}_{5} {SO}_{4}] Br$ and 0.4 mol of $[Co {({NH}_{3})}_{5} Br] {SO}_{4}$ in water to make 4 L of solution. When 2 L of mixture ‘X’ is allowed to react with excess ${AgNO}_{3}$ , it forms precipitate ‘Y’. The rest 2 L of mixture ‘X’ reacts with excess ${BaCl}_{2}$ to form precipitate ‘Z’. Which of the following statements is CORRECT? [2026]

Smart Achievers · Accepted Answer

(4)

$0.4 mol [Co {({NH}_{3})}_{5} {SO}_{4}] Br + 0.4 mol [Co {({NH}_{3})}_{5} Br] {SO}_{4}$ $are present in 4 lit. solution.$

$2 lit. of mixture will contain 0.2 mol of each complex.$

$2 lit. mixture on reaction with excess {AgNO}_{3}, 0.2 mol AgBr will be formed (Y).$

$2 lit. mixture on reaction with excess {BaCl}_{2}, 0.2 mol {BaSO}_{4} will be formed (Z).$

Solution

1 0.4 mol of ‘Z’ is formed.

2 ‘Y’ is ${BaSO}_{4}$ and ‘Z’ is AgBr.

3 0.1 mol of ‘Y’ is formed.

4 0.2 mol of ‘Z’ is formed.
