WebSolution. Verified by Toppr. For the maximum value of the Vant Hoff's factor, we take dissociation constant α as 1, because AlCl 3 undergoes 100% dissociation and every AlCl 3 molecule has turned into one Al 3+ ion and three Cl − ions i.e. total 4 ions are produced. Hence, the value of the Vant Hoff's factor will be equal to 4. Webthe van't Hoff Factor, i The number of ions that form up dissolving a particular ionic solid is called the van't Hoff factorand is often denoted by a lower case i. For molecular solids i=1 since they don't dissociate in water. For ionic compounds, iis equal to the number of …
