Question

Define ionic mobility? What is the unit of ionic mobility?

Answer 1

Ionic mobility:

• The average velocity with which a given ion drifts through a specified medium under the influence of an electric field is called ionic mobility.
• It is denoted by (μ).
• The unit of ionic mobility is m²s^-1 volt^-1.

Explanation:

• The particle’s net charge is directly proportional to its ionic mobility. Ionic mobility is also inversely related to the ion’s stokes radius, which is equal to the effective radius of the moving ion plus any water or other solvent molecules that move with it.
• Electrical mobility is another name for ionic mobility.
• It is defined as the rate at which a charged particle or ion moves through a gas in response to an electric field tugging them.
• Absolute ionic mobility is the mobility with which the ion moves under a unit potential gradient.
