Kool-aid science question!?

Question

Stacey is making a jug of juice and adds Kool-Aid powder to the water until all the powder is dissolved and the solution is saturated. After she does this, she realizes that she used hot water instead of cold water, OPPS! Instead of drinking the hot juice right away, Stacey puts it in the fridge and waits for it to get cold. When the juice is finally ready to drink she notices a lot of powder in the bottom of the jug.

Why is there Kool-Aid powder in the jug now if there wasn't before she out in the fridge?

Answer 1

Kool-Aid is not a pure chemical, but a mixture of ingredients with various properties. However, it is mostly sugar.

You can dissolve an awful lot of Kool-Aid powder in hot water, at least equal parts if the water is really hot and even more if you boil it. A hot saturated sugar solution is more than 99% sugar. A solution like that will solidify rather than settling out. Sugar stays in suspension rather well. It is unlikely to crystallize out after merely chilling in the refrigerator. In fact, when it finally does, it will probably form large sugar crystals, like rock candy.

So if Stacey really did put pounds of Kool-Aid powder into the jug, she didn't follow the directions.

Answer 2

i believe it just settled because it was floaating.  just like rivers the particles settle and pile up
