Many ionic solids, such as silver chloride (AgCl) do not dissolve in water. Because an oxygen is about 16 times more massive than a hydrogen atom, however, the water molecule is nearly nine-tenths oxygen by mass. A:A numerical problem based on Henry's law, which is to be accomplished. Such solutions are called supersaturated solutions and are not stable; given an opportunity (such as dropping a crystal of solute in the solution), the excess solute will precipitate from the solution.The figure below illustrates the above process and shows the distinction between unsaturated and saturated. 0000004697 00000 n Chitosan grafted into mesoporous silica nanoparticles as benznidazol carrier for Chagas diseases treatment.

It is polar, meaning that although it has no net charge, parts of it (in this case the oxygen atom) are slightly negative because of a higher density of electrons, leaving other portions (in this case the hydrogen atoms) slightly positive. Solids dissolving in a liquid solvent (usually water in chemistry experiments) create a solution, and salt dissolving in water is a classic example of how a polar solute behaves in a polar solvent such as H2O.
