• Resumen

  • A remote experiment was developed and carried out to create a phenol/water phase diagram using a low-cost automated data collection system and an online video broadcast. Both the data and video from the experiment were transmitted in real-time. The remote lab experiment was evaluated using qualitative and quantitative questionnaires filled out by the students. The phenol/water phase diagram obtained is entirely consistent, with precision and accuracy compatible with what is expected to be achieved in conventional lab classes. The activity evaluation showed excellent acceptance by the students by doing this lab activity remotely.
