WebSep 15, 2024 · Raoult's law originally was meant to describe the properties of non-electrolytes soltions. When it comes to the solutions of electrolytes, such as salts, you need to introduce the van't Hoff factor, sometimes called isotonic coefficient. To deal with it, you need to know the folmula: i=1+α(n-1), where i - van't Hoff factor α - dissociation degree WebQuestion: Freezing point depression can be used to experimentally determine the van 't Hoff factor of a solute in solution. Given the data in the table, answer the questions below and determine the "real" van 't Hoff factor of the solute.

Analyzing the formula for salt, we have index 1 in Fe and index 3 in Cl, so the number of moles of ions … WebOct 13, 2024 · The extent to which a substance associates or dissociates in a solution is referred to as the Van’t Hoff factor. For instance, when a non-electrolytic substance gets dissolved in water, the value of “i”, in a majority of the cases will be 1.; However, in the formation of a solution in water due to an ionic compound, the value of “i” will remain the …
WebDec 2, 2012 · Let us denote the Van't Hoff factor by i. The i value for a molecule like say glucose (does not dissociate when dissolved in a solvent like water)is generally considered as 1.

Taking the natural log of both sides, we obtain a linear relation between lnK and the standard enthalpies and entropies: lnK = − ΔrHo R 1 T + ΔrSo R. which is known as the van’t Hoff equation. It shows that a plot of lnK vs. 1 / T should be a line with slope − ΔrHo / R and ...
Web1.86 degrees Celsius/molal. What is one way to explain the freezing point depression effect? Consider the solute particles as interfering or standing between the solvent particles. With greater space between the solvent particles, intermolecular forces are weaker. WebJul 21, 2024 · Step by step solution to the problem
WebDec 31, 2013 · Step 2: Determine the van't Hoff factor. The van't Hoff factor, #i#, is the number of moles of particles obtained when 1 mol of a solute dissolves. Nonelectrolytes such as sugar do not dissociate in water. One mole of solid sugar gives one mole of dissolved sugar molecules. For nonelectrolytes, #i = 1#.
