- A solute or substances that completely ionize or dissociates in a solution are known as strong electrolyte. These ions are good conductors of electricity in the solution.
- For example, HCl, HBr, HI, HNO3, NaOH, KOH, etc.
- For strong electrolytes, Λm increases slowly with dilution and can berepresented by the equation:
- It dissociates completely at moderate concentrations.
- The conductance of the solution increases with dilution of solution.
- There exist strong interionic forces of attraction at moderate concentrations.
- The slope for Λm vs c1/2 is linear at low concentrations.
