Electrolytes
  • Solutes whose solutions does not conduct
    electricity are nonelectrolytes. These solution
    are composed of molecules or are pure water.
  • Ionic salts dissolved in water are strong
    electrolytes.
  • Some solutes are poor conductors and are known as
    weak electrolytes.

Electrolytes
  • The ability of a solution to conduct electricity
    is regarded as positive evidence that the
    solution contains ions.
  • Solutions composed of molecules do not conduct
    electricity because there are no ions present.
