Colligative Properties- Finding the van’t Hoff Factor.pdf

WebFor most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1. For most ionic compounds dissolved in water, the van 't Hoff factor is equal to the number of discrete ions in a formula unit of the substance. This is true for ideal solutions only, as occasionally ion pairing occurs in solution. At a given instant a small p WebThe van’t Hofffactor is observed to be slightly less than it is calculated becauseof ion-pairing. It is predicted that theivalues obtained from this lab will be lowerbecause the experiment was not performed in ideal conditions meaning it is more likelytwo opposing ions to temporarily bonded.
