Equilibrium law and le chataliers
« on: February 09, 2013, 12:39:32 PM »
Cu(H20)42+ (aq) + 4 Cl- <--> CuCl42- (aq) + 4 H2O (l)

Is this a heterogeneous or homogeneous reaction?

I would have thought hetero because (aq) and (l) are different. But the book says that H2O takes part of the equilibrium law, suggesting this is homogeneous.

So does adding H2O to the reaction cause it to shift to the left?

Look up the definition of of heterogeneous and homogeneous.

Do water and aqueous solutions mix, or do they form two phases like oil on water?

thanks for your help, I definitely did start by looking up the definition, but i suppose my understanding of phases wasn't as good as i thought.

i apologize for the improper formatting earlier. i fixed it up.

So is it accurate to say that dissolved substances are in the same phase as the solvent?
