Equivalent weight of sulfur in SCl2 is 16,what is the equivalent weight of S in S2Cl2? [S=32,Cl=35.5] I know that the answer is 32. But how how can the equivalent weight of Sulfur be 32? We know that equivalent weight=atomic weight/valency Now sulfur has variable valency of 2,4,6 .So the equivalent weight will be 16,8 and 32/6(as atomic weight of sulfur is 32 ) in different equation.But how can the equivalent weight be 32,when sulfur cannot have a valency of 1? Please exaplain.
