Abstract

The Universidad Estatal a Distancia (UNED) is the public distance-education university in Costa Rica. Since to 2019, the UNED only had available developments and laboratories focused on Physics and Engineering to improve the process of experimentation in distance education. In 2020, the UNED begins to venture into the development of laboratories in the field of chemistry with the peculiarity of working with irreversible processes through the progress of ultra-concurrent laboratories with the support of the global network of real educational laboratories available online, LabsLand. The first development in the field of ultra-concurrent laboratories between UNED and LabsLand was the Acid–Base Titration Laboratory (ABT) at UNED. The laboratory consists on the application of the analytical chemistry technique known as acid–base titration, which is performed by measuring the amount of a reagent of known concentration - called a standard substance – that is consumed by an unknown sample called analyte. Titration methods are used in many routine analyses because they are fast, accurate, convenient, and can be easily automated. Slow addition of the titrant from a burette to a known volume of the analyte solution takes place, until the reaction reaches a chemical neutralization called the “equivalence point”.
