What is the maximum value of vant Hoff factor for Na2SO4.10H2O?
Van’t Hoff is the number of species formed by a compound on dissociation/association in aqueous medium.
Na2SO4.10H2O dissociates in two Na+ ions, one SO42- ion, ten protons and ten hydroxyl ions.
Na2SO4.10H2O 2 Na+ + SO42- + 10 H+ + 10 OH-
So, van’t Hoff factor is sum of the total number of ions formed in dissociation, which is 23.
