Ccl4 van't hoff factor
WebJan 24, 2024 · Ans: The association or dissociation of solute particles in a solution results in a decrease or increase in the molar mass of the solute particles. This results in abnormal molar mass. Van’t Hoff’s “i” factor is used to express this extent of association or dissociation of solutes in solution. Q.5. WebJun 7, 2024 · The Van't Hoff factor isn't an intrinsic property of any species - it depends on the dissociation degree of an electrolyte. Both of those acids are weak and triprotic, meaning they can lose up to three protons in solution (depending on the pH). Therefore, the Van't Hoff factor will likewise change depending on the pH.
