A)The Na₂CO₃ solution has a higher osmotic pressure and higher vapor pressure than the LiCl solution. B)The Na₂CO₃ solution has a higher osmotic pressure and higher boiling point than the LiCl solution. C)The Na₂CO₃ solution has a lower osmotic pressure and lower vapor pressure than the LiCI solution. D)The Na₂CO₃ solution has a lower osmotic pressure and higher boiling point than the LiCl solution. E)None of these statements is true.

The Na2CO3 solution dissociates into three ions (2 Na+ and 1 CO3^2-), while LiCl dissociates into two ions (1 Li+ and 1 Cl-). Therefore, the Na2CO3 solution has a higher osmotic pressure and boiling point elevation due to more particles in solution.
