At infinite dilution, the percentage ionisation of both strong and weak electrolytes is

Options

A. `25%`
B. `10%`
C. `75%`
D. `100%`

Explanation

To solve the question regarding the percentage ionization of strong and weak electrolytes at infinite dilution, we can break it down into the following steps:

### Step 1: Understand the concept of ionization
- Ionization refers to the process by which an electrolyte dissociates into ions when dissolved in a solvent. Strong electrolytes completely dissociate, while weak electrolytes partially dissociate.

### Step 2: Analyze strong electrolytes
- Strong electrolytes, such as HCl, are known to completely dissociate into their constituent ions in solution. This means that their degree of ionization (α) is 1, or 100%, regardless of the dilution.

### Step 3: Analyze weak electrolytes
- Weak electrolytes, like acetic acid, do not completely dissociate in solution. Their degree of ionization (α) is typically less than 1. However, when weak electrolytes are diluted infinitely, the attraction between the ions decreases significantly, allowing for greater ionization.

### Step 4: Determine the effect of infinite dilution
- At infinite dilution, the degree of ionization for weak electrolytes approaches 1 (or 100%). This means that even though weak electrolytes do not fully dissociate under normal conditions, they will do so completely when diluted infinitely.

### Step 5: Conclusion
- Therefore, at infinite dilution, the percentage ionization of both strong and weak electrolytes is 100%.

### Final Answer:
The percentage ionization of both strong and weak electrolytes at infinite dilution is 100%.
