This presentation describes the application of the POGIL methodology to the concepts of chemical equilibrium and pH in an e-learning General Chemistry Course for Engineering students in the Engineering Faculty of the La Plata University in Argentina. In order to develop these topics, our group created activities that contain animated images and interactive simulations. This allows us to introduce these themes to students in an attractive and clear visualization mode, and in such a way that students are able to construct their own knowledge.

As the needed theoretical concepts are developed in the study guide, students interact with the "flash" simulations on their own computers, replying to questions that help them build their own understanding of the topics. Through the social constructivist process that characterizes the POGIL methodology, students work in groups of five to seven students to solve exercises and problems applying the new knowledge to situations of real interest. The facilitator's role is crucial in this process: introducing appropriate questions for each topic, supporting the debate, requesting contributions, and resolving student doubts.

The activity ends with the statement of a problem that involves the most important concepts and requires students to solve it in a collaborative manner.
