Will the SAT Chemistry subject test have questions on topics like standard reduction potentials, calculations for Q, and other types of questions that have complicated formulas (like electrolyte boiling point depression)? There are so many formulas and memorizing them all seems sort of ridiculous.
There is no electrochem on it at all. But no, you don’t need to memorize any of the listed topics.
There’s basic math in chapters like stoichiometry, but nothing too difficult cuz you cant use a calculator
I got a question on boiling point depression once, but it was more of a general, conceptual type of question that didn’t reqire much calculation. I’ve never gotten anything on electrochem though so I wouldn’t worry about that.
Great thanks guys! I know stoich but some of the more random topics were focused on heavily in a review book I read (the Crash Course book) so I was nervous that they would show up.
Boiling point elevation, freezing point depression…
An SAT II question that might test this concept:
At standard temperature and pressure, the boiling point of pure water is 373 K and the melting point is 273 K. When a nonvolatile ionic salt is dissolved in water, which of the following could be the boiling point and melting point of the solution?
(A) 362 K and 282 K
(B) 369 K and 269 K
© 377 K and 277 K
(D) 380 K and 273 K
(E) 376 K and 264 K
Is the answer C? Because ionic salts usually has a high van hoff’s factor and the bigger number of particles the higher the boiling point and melting point, I believe. But i may be wrong.
It’s E – The only choice with a higher boiling point and lower melting point.
Not sure why I said “standard temperature” in the problem wording though.
