what happens when you add MgSO4 to satusated NaCL soln?
« on: February 09, 2012, 01:21:27 PM »
in our experiment, some crystal NaCl formed upon addition of MgSO4...why? i mean is there some governing principle to this shift in equilibrium?

I only know le Chatelier's principle, does it apply to this system and how?

thanks for reading!

are you sure it was crystallized NaCl?

if you were doing the "eye-dropper" solubility rules undergrad lab, where the cells ("wells" if you will) are nearly on top of each other, this may simply be cross contamination

Without my looking up the solubility values (meaning I could be wrong), magnesium sulfate can absorb several moles of water. If so, if the sodium chloride solution were saturated and you removed water, what would happen? Bingo?
