As we learned

 

Vant Hoff factor for dissociation -

i= 1+(n-1)\alpha

Where

n is the no. of dissociated particles

\alpha = degree of dissociation
 

- wherein

NaC l \: \: \: n = 2

CaCl_{2} \: \: \: n = 3

K_{4}[F(CN_{6})]\: \: \: \: \: n=5

 

 Na2SO4 have more osmotic pressure than NaCl solution because Na2SO4 gives 3 ions.

 


Option 1)

Same

Option 2)

Osmotic pressure of NaCl solution will be more than Na2SO4 solution

Option 3)

Osmotic pressure of Na2SO4 solution will be more than NaCl

Option 4)

Osmotic pressure of NaSO4 will be less than that of NaCl solution
