Among the following electrolytes, which is the most effective coagulation agent for Sb_(2)S_(3) solution? (a) Na_(2)SO_(4) (b) CaCl_(2) (c) Al_(2)(SO_(4))_(3) (d) NH_(4)Cl

First I.E. 5d elements are higher than those of 3d and 4d elements. This is due to 1) greater effective nuclear charge action on outer valence electrons. 2) greater effective nuclear charge is experience because of weak shielding effect of 4-f orbitals
