What is i, the van't Hoff term, for the solutes dissolved in water. (assume all dissociate completely): NaCl, NaOH, alcohol(non electrolyte).
NaCl -----------> Na+ + Cl-
NaCl dissociates to 2 ions so
i = 2
NaOH ------------> Na+ + OH-.i = 2
alcohol is non-electrolyte so i = 1
What is i, the van't Hoff term, for the solutes dissolved in water. (assume all dissociate...
The van't Hoff factor for a monoprotic acid dissolved in water is found to be 1.05. When the same acid is dissolved in an unknown solvent, the van't Hoff factor is found to be 1.00. Based on these findings, answer the following questions: 1.) What can you conclude about the strength of the acid? Clearly and completely explain how you came to your conclusion. 2.) What can you conclude about the polarity of the unknown solvent? Clearly and completely explain...
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.
Solutes do not typically exhibit ideal behavior in solution, resulting in non-integer van't Hoff factors. Based on this information, which of the following solutes is most likely present in a 2.12 m aqueous solution with a boiling point of 103.87°C? (Kb for water is 0.512°C/m) NaBr C6H12O6 Na3PO4 Ca(ClO3)2
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
QUESTION 2 Solutes that when dissolved in water totally dissociate into ions and conduct electricity very well are: 1. Strong electrolytes 2. Weak electrolytes 3. Nonelectrolytes
At what temperature would a 1.40 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86 ∘C/m . Express your answer with the appropriate units.
5) At what temperature would a 1.55 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86 .C/m. The freezing point for pure water is 0.0 °C and Kf is equal to 1.86 °C/m.
What is the predicted van't Hoff factor for Mg3N2 I think it is 5 but I am second guessing myself...
what is the actual van't hoff factor for an aqueous 0.20 molal solution of FeCl3 if the freezing point is -1.2C? assume the Kf of water is 1.86C/m
