Bonus Question During the phenomenon of osmosis, the semi-permeable membrane only allows particles of the solvent to cross from one side to the other. In a saline solution (water + NaCl), the water molecules (the solvent) are larger (~140-150 pm) than the sodium ions (~100 pm). If no chemical interaction occurs between the membrane and the ions, how can the water molecules cross the membrane while the smaller sodium ions cannot? -150 pm HH Membrane ~100 pm Na

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
