exam is coming up in a few days and i am stuck with a couple of things:
1. How do you know if something is a strong electrolyte or not?
2. Which of these would you expect to be soluble in the nonpolar solvent carbon disulfide, CS2? a) SnS2 b) CaCO3 c) CI4 d) H20
(i thought it would be H20 but the answer is actually CI4...i dont get it)
3. Which of the following aqueous solutions will have the lowest freezing poing? a) 1M MgBr2 b) 1M KBr c) 2M C6H1206 d) 2M C12H22O11. (This question has something to do with colligative properties but i dont know how to work it out)
4. How to find pH from molarity? (Q. What is the pH of a 0.01M hydrochloric acid solution?)
5. How to know if a compound is a good/poor hydrogen ion donor/acceptor from knowing the Ka?
Any help on any of the questions would be much, much, MUCH appreciated, thankyou!
Oh and please show any working that you do to work them out.
