It is recommended to take this subject once the subjects of Physical Chemistry I and II of the second year have been passed. It is also considered important to take this subject simultaneously or later to the subject Physical Chemistry IV. It is considered very important for student learning process to respect the order of the subjects established in the curriculum.
The subject of Physical Chemistry V is the last scheduled subject of the Physical Chemistry Matter and it shows the importance of surfaces in chemistry. Thus, we start by reviewing the superficial phenomena and studying the processes of adsorption and heterogeneous catalysis in topic 1, going on in topic 2 to make an introduction to the study of macromolecules and colloidal systems, whose properties are determined in large part by its high surface. The rest of the subject is devoted to reviewing the essential aspects of Electrochemistry, a branch of Physical Chemistry that studies the behavior of electrolyte solutions and the electrode processes that occur on a surface, both in equilibrium and its kinetic behavior. It has as fundamental fact the transport of charge from one phase to another, then it is, therefore, a branch of surface chemistry. Electrochemical kinetics and heterogeneous catalysis can also be considered part of the Chemical Kinetics that is studied in the subject of Physical Chemistry IV.

Unit 9 (de 11): Topic 9 PRACTICE 2. DETERMINATION OF THE AVERAGE MOLECULAR WEIGHT OF A POLYMER BY VISCOSITY MEASUREMENTS. The viscosity of different solutions of a polymer (cellulose acetate) is determined using an Ostwald viscometer. From the viscosities measured, the specific viscosity of each solution is obtained. The intrinsic viscosity is determined from the appropriate representation of a function of the specific viscosity against the concentration of the polymer. From it and using the Mark-Houwkin-Sakurada equation, the average molecular weight of the polymer is calculated. | |

Unit 10 (de 11): Topic 10 PRACTICE 3. DETERMINATION OF THE DISSOCIATION CONSTANT OF A WEAK ACID BY CONDUCTIMETRY. The dissociation constant of acetic acid is determined from measurements of the specific conductivity of several solutions of different concentrations. The molar conductivities of the different solutions are calculated and, given the molar conductivity at infinite dilution, the degree of dissociation of the acid is determined by applying the Arrhenius equation. From the appropriate representation of the Ostwald dilution law we obtain, from the ordinate at the origin, the molar conductivity to infinite dilution and from the slope, the dissociation constant. The goodness of the Arrhenius equation is verified using an iterative procedure to calculate the degree of dissociation. | |

Unit 11 (de 11): Topic 11 PRACTICE 4. GALVANIC BATTERIES: ASSEMBLY AND DETERMINATION OF THERMODYNAMIC PROPERTIES FROM MEASUREMENTS OF THE ELECTROMOTIVE FORCE. In this practice three types of galvanic batteries are built: a concentration battery in the electrolyte (with silver electrodes, silver nitrate electrolyte and salt bridge of ammonium nitrate), a battery without transport with different electrodes and electrolytes and a standard or Clark battery. The measurement of electromotive force (EMF) of these cells is used to verify the Nernst equation (first cell) and determine the solubility product of the AgCl (second cell). In the case of the Clark battery, the measurement of the EMF at different temperatures between 25 and 45 ºC allows us to determine the variation of enthalpy, entropy and free energy of the chemical reaction of the battery. | |
