What is the difference between strong and weak electrolytes?

Electrolysis is the process of passing an electric current through a substance in the molten or aqueous state thereby decomposing it. Electrodes, electrolytes and salt solution are the major components involved in the process of electrolysis. Electrolyte plays a major role in the process. Let us read more about it.

What is an electrolyte?

An electrolyte is a substance that dissociates in water into charged particles called ions. Positively charged ions are called cations. Negatively charged ions are called anions. Simply, an electrolyte is a substance that can conduct an electric current when melted or dissolved in water.

Types of electrolyte

  • Strong Electrolytes – Electrolytes are chemical species that conduct electricity when dissolved in solution.
  • Weak electrolytes – An electrolyte that ionises to a small extent in solution is called weak electrolyte.

The difference between strong and weak electrolytes

The difference between strong and weak electrolytes are tabulated below.

Strong electrolyte Weak electrolyte
The electrolytes which are completely ionised, called strong electrolytes. The electrolytes which are partially ionised called strong electrolytes.
The extension of ionisation is more. The extension of ionisation is less.
They have high electrical conductivity. They have low electrical conductivity.
