Carboxylic modified spherical mesoporous silicas as drug delivery carriers. Several substances\(\ce{HCl}\), \(\ce{NH_3}\), and \(\ce{SO_2}\)have solubility that decreases as temperature increases. This process represents a physical change known as dissociation. This is an example of exothermic reaction in which heat is liberated along with the products so when a little sulfuric acid is added to water in a beaker, the water becomes hot. When some substances are dissolved in water, they undergo either a physical or a chemical change that yields ions in solution. ; Alves, O.L.

A:The Gibbs Duhem equation for binary mixture is written as follow: Q:Several emergent properties of water contribute to the suitability of the environment for life. The stronger covalent bonds of water (which is also held together generally by hydrogen bonds between water molecules) win out, and NaCl is pulled apart, with the Na+ and Cl_ ions setting loosely in place between the intact H2O molecules. If the added solute dissolves, then the original solution was unsaturated. Popova, M.D. Notice how the temperature dependence of \(\ce{NaCl}\) is fairly flat, meaning that an increase in temperature has relatively little effect on the solubility of \(\ce{NaCl}\).
