You are given a small beaker of solution at room temp. You add a bit of solute to the solution and it dissolves. The solution was:
saturated
unsaturated
concentrated
warm
How do you know when you have a saturated solution?
You don't see anymore material in the solution. It has dissolved.
The material dissolves and no more will dissolve because you see it collect at the bottom.
The solution is bubbling and cloudy.
The solution is clear and there is nothing at the bottom.
