WebIt is also important to understand the role of the vanā€™t Hoff factor. For example, a 2.0 molal solution of NaCl has a particle concentration equal to 4.0 molal since each formula unit splits into two pieces (Na+ and Cl-) creating twice the number of free floating particles (ions). In this case the ideal vanā€™t Hoff factor equals two.

WebSolution. Verified by Toppr. For the maximum value of the Vant Hoff's factor, we take dissociation constant Ī± as 1, because AlCl 3 undergoes 100% dissociation and every AlCl 3 molecule has turned into one Al 3+ ion and three Cl āˆ’ ions i.e. total 4 ions are produced. Hence, the value of the Vant Hoff's factor will be equal to 4. WebJul 26, 2014 Ā· 1. The van't hoff factor for CaCL2 is 2.71.
