Weak acids and weak bases are weak electrolytes.
Substances that dissociates into ions to a lesser extent are called weak electrolytes. Their solutions contain both ions and molecules. Example: Ammonium acetate, ammonium hydroxide, acetic acid, carbonic acid, ammonia, phosphoric acid etc.
- A weak electrolyte is a solution in which only a small fraction of the dissolved solute exists as ions.
- Water is also considered to be a weak electrolyte. That is, only a small fraction of the H2O molecules in water dissociate to form H+ and OH– ions.
