Two open beakers one containing a solvent and the other containing a mixture of that solvent with non volatile solute are together sealed in a container. Over time:
Option: 1 the volume of the solution and the solvent does not change
Option: 2 the volume of the solution increases and the volume of the solvent decreases
Option: 3the volume of the solution decreases and the volume of the solvent increases
Option: 4 the volume of the solution does not change and the volume of the solvent decreases.
5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
