Worked practice questions

Colligative property equations are corrected using the factor of:

  1. Raoult only
  2. Henry only
  3. Dalton only
  4. Van't Hoff
Show answer and solution

Correct answer: D. Van't Hoff

1. Some solutes dissociate or associate in solution. 2. The particle count then differs from what was assumed. 3. The van't Hoff factor corrects for that. _Source: syllabus Chemistry Part I, Chapter 2, Solutions._
