    If you mean less exothermic than yes.
    no i mean more exothermic

    Lattice + Solution = Hydration

    So if hydration = - 2000 Kj
    then lattice has to <-2000 Kj ie less exothermic

    so hydration is more exothermic than lattice enthalpy

    Why does lattice have to be < -2000
    Enthalpy of solution can be +ve or -ve

    Yeah it it's a bit abstract, but as long as you try and picture the cycle, it makes things slightly easier I find.

    Yep, another word for it is "permanent pink" I believe, as it is in the textbook page 219.

    Feeling reasonably good about this exam. Just revised back over my notes for chapter 1 and done the practice questions again and am getting pretty much all of them right. Going to take short break then crack on with chapter 2 revision. I'm just hoping the paper isn't stupidly hard tomorrow.

    How is everyone else doing?
