Question -
If α is the degree of dissociation of Na2SO4, the vant Hoff's factor (i) used for calculating the molecular mass is
Options:
A .  1+α
B .  α
C .  1+2α
D .  1−2α
Answer: Option C : C Na2SO41−α⇌2Na+2α+SO2−4α Totalno. ofionsafter dissociation = 1+2α vant Hoff's factor,i=No.ofparticlesafterdissociationNo.ofparticlesbeforedissociation=1+2α
