Question

Consider the separate solution of 0.500 M C₂H₅OH (aq.), 0.100 M Mg₃(PO₄)₂ (aq.), 0.250 M KBr (aq.) and 0.125 M Na₃PO₄ (aq.) at 25°C. Which statement is true about these solutions, assuming all salts to be strong electrolytes?

Options

• They all have same osmotic pressure.

• 0.100 M Mg₃(PO₄)₂ (aq.) has the highest osmotic pressure.

• 0.125 M Na₃PO₄ (aq.) has the highest osmotic pressure.

• 0.500 M C₂H₅OH (aq.) has the highest osmotic pressure.

Answer 1

They all have same osmotic pressure.
