Question

I don't want an answer. All I want to know is if you can tell whether something is a liquid/solid/gas just based on a solubility curve? And if so, how?

On the basis of the solubility curve for KNO3 what type of substance would you expect KNO3 to be?

liquid
solid
gas
It's impossible to tell.

Answer 1

I know KNO3 is a solid, but I just don't know if you can tell that just by looking at the solubility curve. I didn't find it out that way, I had to look it up.

Answer 2

For some reason I cannot view the picture.

Answer 3

Huh, wonder why it's not working. Here is a different one. It's basically the same thing. Let me know if it doesn't work.

Answer 4

If not, just look up "solubility curve of KNO3"

Answer 5

Sorry about that!

Answer 6

It's ok. Look what I found: http://quizlet.com/4407385/state-of-mattersolubility-flash-cards/

Somewhere in there it states that when the temperature decreases the solubility of solids and liquids decreases.

Maybe you can look up more special characteristics like that.
