Chemistry / Unit 3 Chem 0406 short lesson, about 20 seconds
Strong and Weak Electrolytes
Captions available
The idea
A strong electrolyte dissociates completely into ions in solution; a weak electrolyte dissociates only partially.
In practice
Dissolved NaOH exists almost entirely as Na+ and OH− ions, while dissolved ammonia stays mostly as intact NH3.
Where people slip
"Strong" describes how completely a solute dissociates, never how much is dissolved — that idea gets its own name next.
