Difference between Strong Electrolytes and Weak Electrolytes (Strong Electrolytes and Weak Electrolytes)

Electrolytes which ionize almost completely in solutions are known as strong electrolytes while electrolytes which ionize only to a small extent in solutions are known as weak electrolytes.

Difference between: Strong Electrolytes and Weak Electrolytes

Strong Electrolytes

Strong Electrolytes

1. Completely dissociated at moderate concentrations

2. Conductance increases with dilution but the increase is only slight.

3. There are strong interionic attraction at moderate concentrations.

4. The λm vs √c plot is linear at low concentrations.

Weak Electrolytes

Weak Electrolytes

1. Not completely dissociated at moderate concentrations

2. Conductance increases rapidly with dilution especially near infinite dilution

3. Interionic attractions are not strong even at higher concentrations

4. The λm vs √c plot is not linear even at low concentrations.
