The degree of dissociation of a weak electrolyte is ...........one whereas that of a strong electrolyte is ............one.

Answer

To solve the question regarding the degree of dissociation of weak and strong electrolytes, we can follow these steps:

### Step 1: Define Degree of Dissociation
The degree of dissociation (α) refers to the fraction of the total number of solute particles that dissociate into ions when dissolved in a solvent. It is expressed as a value between 0 and 1.

### Step 2: Analyze Weak Electrolytes
Weak electrolytes are substances that do not completely ionize in solution. This means that only a fraction of the solute molecules dissociate into ions. Therefore, the degree of dissociation for a weak electrolyte is less than one (α < 1).

### Step 3: Analyze Strong Electrolytes
Strong electrolytes, on the other hand, are substances that completely ionize in solution. This means that all of the solute molecules dissociate into ions. Therefore, the degree of dissociation for a strong electrolyte is equal to one (α = 1).

### Step 4: Conclusion
In conclusion, the degree of dissociation of a weak electrolyte is **less than one**, whereas that of a strong electrolyte is **equal to one**.

### Final Answer
The degree of dissociation of a weak electrolyte is **less than one** whereas that of a strong electrolyte is **equal to one**.
