Abstract	Traditionally, laboratory practice aims to establish schemas learned by students in theoretical courses through concrete experiences. However, access to laboratories might not always be available to students. Therefore, it is advantageous to diversify the tools that students could use to train practical skills. This technology report describes the design, development, and first testing of a mobile augmented reality application that enables a hands-on learning experience of a titration experiment. Additionally, it presents the extension of the TrainAR framework for chemical education through the implementation of specific domain features, i.e., logbook, graph, and practical oriented hints. To test the application, 15 participants were recruited from five different high schools and two universities in Belgium. The findings reflect that the MAR Lab app was well-received by the users. In addition, they valued the design elements (e.g., logbook and multiple-choice questions), and the system has "good" usability (SUS score 72.8, SD = 14.0). Nevertheless, the usability and learners' experience can be improved by tackling technical problems, providing more explicit instructions for subtasks, and modifying certain features. Therefore, future development will concentrate on improving upon these shortcomings, adding additional levels to target a larger audience, and evaluating the improvements' effects with more participants.
