A blog for the physical chemistry course sequence at Cal Poly, particularly CHEM 351, 352, and 353.
From what you said in class today, I don't think problems 11 to 13 from homework 3 will appear quantitavely on the exam, but should we worry about the book problems 17-28, 17-32, and 17-33?
I know that this doesn't have anything to do with the homework solutions, but did you say in class that the midterm is in Fisher Science(33) room 206, or in Science North (53) room 206? Because I think I might have written it down wrong...
a)problem 17.28 is simple -- plot molar conductivity versus sqrt(c) and see if linear or not. extrapolate to zero to get infinite dilution. now you don't have to do it (you're welcome). problem 17.32 is nearly identical to the one i did in class and might be worth the three minutes of effort.problem 17.33 will have to wait.b) Science North 53-206 is where the pchem party will be held. be there!
i can't remember what you said about why the molar conductivity at infinite dilution (in relation to the law of independent migration) is larger for potassium than sodium when it's kind of counter-intuitive since potassium is larger. could you remind me again please?
The ion-dipole force between sodium ion and water is greater than that for potassium ion, which results in sodium ion dragging more waters along with it.
the blog died. :(
i miss the blog.
i miss the blog as well
