B. Quantity of electricity passed
C. Nature of vessel used
D. Nature of solute molecules

Answer

To determine the factors on which the degree of ionization of a compound depends, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Degree of Ionization**:
- The degree of ionization refers to the extent to which a solute dissociates into ions in a solution. This is particularly relevant for electrolytes, which can be classified as strong or weak.

2. **Identifying Factors**:
- The degree of ionization depends on three main factors:
- **Nature of the Solute**: The type of solute (strong or weak electrolyte) significantly influences ionization. Strong electrolytes (like NaCl) dissociate completely in solution, while weak electrolytes (like acetic acid) dissociate partially.
- **Concentration of the Solution**: The concentration of the solute affects the degree of ionization. Generally, as the concentration increases, the degree of ionization may decrease for weak electrolytes due to the common ion effect.
- **Temperature**: The degree of ionization is also affected by temperature. Increasing the temperature typically increases the degree of dissociation for most solutes, leading to a higher degree of ionization.

3. **Conclusion**:
- Therefore, the degree of ionization of a compound depends on:
- The nature of the solute (strong vs. weak electrolytes)
- The concentration of the solution
- The temperature of the solution

### Summary of Factors:
- **Nature of Solute**: Strong electrolytes dissociate more completely than weak electrolytes.
- **Concentration**: Higher concentration can lead to decreased ionization for weak electrolytes.
- **Temperature**: Higher temperatures generally increase ionization.
