Formación de las Soluciones
There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a…
Las Fuerzas Intermoleculares en las Soluciones
The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without energy from some…
Entalpía de Solución
There are two criteria that favor, but do not guarantee, the spontaneous formation of a solution: A decrease in the internal energy of the system…
Soluciones Acuosas y Calores de Hidratación
Water and other polar molecules are attracted to ions. The electrostatic attraction between an ion and a molecule with a dipole is called an…
Equilibrio y Saturación de las Soluciones
Imagine adding a small amount of sugar to a glass of water, stirring until all the sugar has dissolved, and then adding a bit more. You can repeat…
Propiedades Físicas que Afectan la Solubilidad
Solutions of Gases in Liquids As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between…
Expresando la concentración de las Soluciones
A solute is a component of a solution that is typically present at a much lower concentration than the solvent. Solute concentrations are often…
Reducción de la Presión de Vapor
The equilibrium vapor pressure of a liquid is the pressure exerted by its gaseous phase when vaporization and condensation are occurring at equal…
Soluciones Ideales
According to Raoult’s law, the partial vapor pressure of a solvent in a solution is equal or identical to the vapor pressure of the pure…
Descenso del punto de Congelamiento y Elevación del Punto de Ebullición
Boiling Point Elevation The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since…
Ósmosis y Presión Osmótica de las Soluciones
A number of natural and synthetic materials exhibit selective permeation, meaning that only molecules or ions of a certain size, shape, polarity,…
Electrolitos: Factor de van't Hoff
Colligative Properties of Electrolytes The colligative properties of a solution depend only on the number, not on the identity, of solute species…
Coloides
Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as…
Estudio de la adsorción corta de péptidos en nanopartículas inorgánicas dispersas en soluciones mediante el método de agotamiento
Fundamentals of inorganic-organic interactions are critically important in the discovery and development of novel biointerfaces amenable for…
Síntesis y caracterización de supramoleculares Coloides
Control over colloidal assembly is of utmost importance for the development of functional colloidal materials with tailored structural and mechanical…
Formación material de la araña recombinante sedas a través de la Solvación acuosa utilizando calor y presión
Many spiders produce seven types of silks. Six of the silks are fiber in form when produced by the spiders. These fibers are not water soluble. In…
