Question:
1 L, 0.02 M solution of [Co(NH3)5 SO4]Br is mixed with 1 L, 0.02 M solution of [Co(NH3)5Br]SO4. The resulting solution is divided into two equal parts (X) and treated with excess of AgNO3 solution and BaCl2 solution respectively as shown below:
1 L Solution (X) + AgNO3 solution (excess) → Y
1 L Solution (X) + BaCl2 solution (excess) → Z
The number of moles of Y and Z respectively are

The Correct Option is C
Solution and Explanation
\[
\left[ \text{Co}(NH_3)_5SO_4 \right]Br + \text{AgNO}_3 \rightarrow \text{AgBr} \downarrow
\]
\[
0.01 \text{ mol} \quad \text{excess} \quad 0.01 \text{ Mol}
\]
\[
\left[ \text{Co}(NH_3)_5Br \right]SO_4 + \text{BaCl}_2 \rightarrow \text{BaSO}_4 \downarrow
\]
\[
0.01 \text{ mol} \quad \text{excess} \quad 0.01 \text{ Mol}
\]
Thus, the correct answer is 0.01 moles for both Y and Z.

Solutions
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
Types of Solutions:
The solutions can be classified into three types:
- Solid Solutions - In these solutions, the solvent is in a Solid-state.
- Liquid Solutions- In these solutions, the solvent is in a Liquid state.
- Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
- Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
- Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
- Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
