What is saturated?

A saturated solution is one that can’t hold any more stuff inside it, like a sponge that’s completely soaked.

Imagine you have a glass of water and you start adding sugar, one spoon at a time. At first, the sugar dissolves easily, and the water stays sweet. But if you keep adding more and more sugar, eventually there will be little bits of sugar at the bottom that won’t dissolve, no matter how much you stir.

That’s saturated, when a liquid can’t hold any more of a substance because it’s already full up.

If you add even more sugar to the glass and then heat the water, the extra sugar might start dissolving again. But if you let the solution cool down, the sugar that was dissolved will come out of the water, like when you leave a sweet drink in the fridge and it turns into syrup.

So, saturated means "full up", just like a cup full of juice can’t take any more fruit pieces inside. A saturated solution is one that can’t hold any more stuff inside it, like a sponge that’s completely soaked.
