An electrolyte is:
A compound that dissociates (breaks apart) into positive and negative ions when it dissolves in water.
These free-moving ions carry electric current through the solution.
A solution that has dissolved the maximum amount of solute possible at a specific temperature.
If you add more solute, it won’t dissolve — it just sinks to the bottom.
Example: You keep adding salt to water and stirring, but eventually, the salt stops dissolving — that’s when the solution is saturated.
A solution that has not yet reached the maximum solute amount it can hold.
You can still dissolve more solute in it.
Example: A spoon of sugar in tea — it fully dissolves, and you could add more — this is unsaturated.
Type | Definition | Example |
---|---|---|
Homogeneous Mixture | Looks like a single substance; same throughout | Salt water, air, alloy (like brass) |
Heterogeneous Mixture | You can see different parts; uneven composition | Salad, oil & water, sand in water |
