al2(so4)3 because k4Fe(CN)6 on dissosiation gives 4 K+ and 1 Fe(CN)6- ions.i is defined as ratio of no of moles after dissosiation to no of moles before dissosiation. in this case 5/1=5. in case of Al2(So4)3 we have 2 Al3+ and 3 SO4 2- therefore 5 after and 1 mole of Al2(So4)3 before. please approve if correct. thanks
