Which of the following compounds has the lowest van't Hoff factor? What is the van't Hoff factor of NaNO3, Na3PO4, Li2CO3, MgCl2? I calculated them all to be (in order) a van't Hoff factor of 4, 7, 5, and 3. However the lowest van't Hoff factor went to NaNO3. Why?
Ideally, the van't Hoff factor, i, can be determined by the following equation [i = moles of particles/moles of dissolved solute] What I the van't Hoff factor for BeCl_2? 1 2 3 4
The boiling point of an aqueous 3.0M ethylene glycol (C2H6O2) solution is 102oC and the freezing point is-10.8oC. What is the experimental van't Hoff factor (i) and how does it compare to the theoretical van't Hoff factor?
Post Laboratory Questions: 1. Predict the value for the Van't Hoff factor, i, for each of the following compounds. (a) Mg(NO3)2 (b) CaSO4 (c) C12H22011 (sucrose) 2. Which of the following compounds would you expect to be the best at lowering the freezing point of water: sucrose, LiCI, SrCl2, Na2S, AICl3, or MgaN2 and why? Assume all are ionic compounds except sucrose and all are soluble in water and equal amounts (moles) are used?
1. What is the expected van't Hoff factor for FeCl3? (Assume dilute conditions) A) 1 B) 2 D) 4 C) 3 E) 5 2. Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. A) 0.100 mol kg-1 NaCl B) 0.100 mol kg-1 AlCl3 C) 0.100 mol kg-1 MgCl2 D) 0.100 mol kg-1 C6H1206 E) They all have the same boiling point.
