The value of `Kb` depends upon the:

Options

A. nature of the solvent
B. nature of the solute
C. nature of the solution
D. Both (b) and (c)

Explanation

To answer the question regarding the factors that the value of \( K_b \) (the base dissociation constant) depends upon, we can break down the solution into several steps:

### Step-by-Step Solution:

1. **Understanding \( K_b \)**:
- \( K_b \) is a measure of the strength of a base in solution. It quantifies the extent to which a base can dissociate in water to produce hydroxide ions (OH⁻).

2. **Factors Affecting \( K_b \)**:
- The value of \( K_b \) is influenced by several factors, including:
- **Nature of the Base**: Different bases have different strengths. For example, strong bases like NaOH have a higher \( K_b \) compared to weak bases like NH₃.
- **Temperature**: The value of \( K_b \) can change with temperature. Generally, as temperature increases, the dissociation of the base may increase, leading to a higher \( K_b \).
- **Solvent**: The solvent in which the base is dissolved can also affect \( K_b \). For example, \( K_b \) values can differ in non-aqueous solvents compared to water.

3. **Conclusion**:
- In summary, the value of \( K_b \) depends on the nature of the base, the temperature of the solution, and the solvent used.

### Final Answer:
The value of \( K_b \) depends upon the nature of the base, temperature, and the solvent.
