Consider separate solution of 0.5 M C_(2)H_(5)OH(aq), 0.1 M Mg_(3)(PO_(4))_(2)(aq), 0.25 M KBr(aq) and 0.125 M Na_(3)PO_(4)(aq) at 25^(@)C which statement is true about these solutions, assuming all salts to be strong electrolytes ?

Answer»

They all have the same osmotic PRESSURE
`0.1 M Mg_(3)(PO_(4))_(2)(aq)` has the highest osmotic pressure
`0.125 M Na_(3)PO_(4)(aq)` has the highest osmotic pressure
`0.5 M C_(2)H_(5)OH(aq)` has the highest osmotic pressure
