Which of the following analytical chemical statements regarding the Van't Hoff factor () are mathema — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

For complete trimerization, $\alpha=1$, so $i = 1 + 1(1/3 - 1) = 1/3 = 0.333$ (A). For a binary weak electrolyte ($n=2$), $i = 1 + \alpha(2-1) = 1 + \alpha$. If $\alpha=0.5$, $i=1.5$ (C). Statement D correctly provides the classic textbook definition of $i$. Statement B is false; non-electrolytes that neither dissociate nor associate have $i = 1$, because they remain as intact single molecules in solution, not zero.
