Sales: reacciones químicas y aplicaciones (edX)

Offered by Universitat Politècnica de València, UPValenciaX,
Sales: reacciones químicas y aplicaciones (edX)

Avanzando en el conocimiento de las sustancias que modifican la acidez del medio, este curso de química se dedica a estudiar los equilibrios en que intervienen sales. En este curso en línea se tratan en primer lugar, las sales como compuestos que pueden modificar la acidez del medio.

La explicación de dichas modificaciones se realiza a partir de la teoría de Brönsted-Lowry. Estos conceptos se aplican al cálculo de las concentraciones de las diferentes especies en disolución justificando adecuadamente las aproximaciones realizadas y poniendo especial énfasis en el cálculo del pH.
En este curso de química se describe la naturaleza y aplicaciones de las disoluciones amortiguadoras, citando algunos ejemplos representativos de su importancia en el medio natural. El estudio de los equilibrios ácido-base en este contexto se centra en el cálculo del pH de dichas disoluciones y en sus modificaciones cuando se añaden cantidades limitadas de ácidos o bases fuertes.
This course is part of the Fundamentos de Química XSeries.

What you'll learn

  • Estudiar los equilibrios en que intervienen sales

Learn how to generate ideas at the interface between chemistry and biology. Chemistry and biology are traditionally taught as separate subjects at the high school level, where students memorize fundamental scientific principles that are universally accepted. However, at the university level and in industry, we learn that science is not as simple as we once thought. We are constantly confronted by questions about the unknown and required to use creative, integrated approaches to solve these problems.
