Dear Friend,
Only your " analysis" is wrong.Le Ch's principle describes an equilibrium
with reactants A, B with products C, D( not A or B)- while dissolution is
governed by thermochemistry. You may please refer text books to clear. No
problem.
Thanks and regards,
Sisir Adhikari

Subject: ORGLIST:Le Chatelier's Principle
I have been asked how to apply Le Chatelier's principle in the following
situation:
When you dissolve NaOH in water to form a saturated solution, heat evolves.
The reaction is exothermic.
According to Le Chatelier's principle, transferring heat to the system would
move the equlibrium to the left, and NaOH should precipitate out. However,
when heat is introduced into the system, more NaOH dissolves.
What is wrong with NaOH, or Le Chateliers principle, or my analysis?
regards
Thomas
