Osmotic pressure of 0.1 M solution of NaCl and Na2SO4 will be
Same
Osmotic pressure of NaCl solution will be more than Na2SO4 solution
Osmotic pressure of Na2SO4 solution will be more than NaCl
Osmotic pressure of Na2SO4 will be less than that of NaCl solution
Na2SO4 have more osmotic pressure than NaCl solution because Na2SO4 gives 3 ions.
