Homework Help: Solubility of KNO3

  1. Mar 21, 2007 #1
    Hey.. Sorry to be so dopey but I'm unable to write a valid hypothesis about the solubility of KNO3 in water as temperature increases...

    I'm unsure which laws apply and how to write up a decent standard hypothesis.. could you possibly give me a few key terms I could research or write a few sentences explaining? thanks :)

    The "reaction" is:

    KNO3 + Heat <-------> K+(aq) + NO3-(aq)

    which is another way of saying that the precipitation of potassium nitrate is exothermic.

    Any help?
