For example CHCL3 or Ethanol or SF4...ya know, solvents and solutes and stuff like that?

gosh...I hope im making sense... :p


For example one of my probs. was to circle the solute that will dissolve to a greater extent at room temp.

solvent: Water (H2O)
solute choices: CHCL3 or CCl4

Question: Determine the average molarity of the [unknown] acid solution by using the difference in volume of NaOH added between the first inflection point (i'm guessing they're talkin bout the equivalence point) and the seconf inflection point??

btw...this is a titration lab and i have to try and identify the unknown acid, which *hint* is a polyprotic acid....i just don't have a clue where to start...what equation should i, could i use? ANY IDEAS!! whatever you have...help!

How would one (in theory) be able to verify or test to determine the monoprotic or diprotic nature of an unknown acid without a pH probe for a titration (assuming the acid is not any other polyprotic)?

This is probably one of those "duh" questions, but I can't think of anything.

Which of the following are true statements ?


a) At equilibrium DGreaction = 0

b) Q > Keq when DGreaction < 0

c) When Q > Keq addtional products are formed

d) When Q = Keq ln Q = 1

e) When Q > Keq the amount of products will decrease


You must enter all true statements in one lower case alphabetical group, with no spaces between the letters you of your answer.

What is some evidence in acid-base reactions? In other words, when observing an acid-base reaction, what might one see? Also, is HC2H3O2 + CaOH and acid-base reaction and if so, how would you write the balanced equation. Thanks!

For each of the solvents below, choose the solute that will dissolve to a greater extent at room temp.

Solvent ♥ Solute Choices
Water (H2O) ♥ CHCl3 or CCl4

Ethanol (C2H5OH) ♥KOH or BBr3

Methaol (CH3OH) ♥ BrF3 or SbF5

Pentane (C5H12) ♥ SF4 or SF6

Propanol (C3H7OH) ♥ C6H14 or H2O

If you have the answer PLEASE PLEASE tell me how you got it!? thanks! ♥
