Explain why equimolar aqueous solution chloride and sodium sulphate are not isotonic? |
| Answer» Solution :NaCl DISSOCIATES to give 2 ions`(NA^(+) and Cl^(-)). Na_(2)SO_(4)` dissociates to give 3 ions `(2Na^(+) and SO_(4)^(2-))`. Thus, EQUIMOLAR solution of NaCl and `Na_(2)SO_(4)` have different concentrations of ions in the solution. As osmotic pressure depends upon concentration of particles in the solution, they have different osmotic pressures. | |
