Q. If $α$ is the degree of dissociation of $N a_{2} S O_{4}$ , the vant Hoff’s factor $(i)$ used for calculating the molecular mass is

$1 + α$

$1 - α$

$1 + 2 α$

$1 - 2 α$

van’t Hoff factor $(i) = \frac{1 - α + 2 α + α}{1} = 1 + 2 α$

Q. If α is the degree of dissociation of Na2​SO4​, the vant Hoff’s factor (i) used for calculating the molecular mass is

1+α

1−α

1+2α

1−2α
