abstract={In modern chemistry education, interactive digital tools play a crucial role in enhancing student engagement and comprehension. This study presents <i>pK explorer</i>, an interactive online dashboard designed to facilitate the visualization and analysis of acid-base titration curves, as well as the pH-dependent behavior of key physicochemical parameters such as lipophilicity and solubility. Developed using R Shiny and Quarto, these dashboards provide a user-friendly interface where students can manipulate input variables and observe real-time graphical changes with ease, fostering a deeper understanding of complex chemical concepts. Traditional teaching methods often struggle to convey the dynamic nature of acid-base equilibria, particularly in relation to titration curve interpretation. By offering customizable inputs and interactive graphing, <i>pK explorer</i> allows students to explore the effects of dilution, ionic strength, and activity corrections on titration behavior. Furthermore, the dashboard extends beyond acid-base chemistry by integrating solubility and lipophilicity modeling, enabling students to examine how these properties vary with pH ¡ª a key concept in pharmaceutical and analytical chemistry. The combination of R Shiny¡¯s computational power with Quarto¡¯s flexible design framework results in an accessible and highly adaptable educational tool. This dashboard aligns with contemporary pedagogical approaches that emphasize interactive and student-driven learning experiences. By integrating technology into chemistry education, <i>pK explorer</i> serves as both a self-guided learning platform for students and a valuable teaching aid for instructors. The primary aim of this work is to promote the use of this open-access tool among educators and to encourage the development of more interactive, gamified educational resources that enhance learning experiences. The open-access nature of this tool ensures that it can be widely utilized and further developed by others to support diverse educational needs in chemistry, medicine, and related disciplines.},
