Virtual Laboratory for Solution Preparation and Solubility

Abstract

Description A web-based interactive virtual environment designed for teaching solution preparation and solubility equilibrium. This resource runs in any modern browser (desktop and mobile) and functions as both a virtual laboratory and a pre-laboratory tool, featuring precise virtual instrumentation, including a magnetic stirrer with precise speed and temperature control. It allows students to explore the relationship between kinetic variables, such as agitation, and thermodynamic constraints associated with saturation and equilibrium. Users can practice preparing solutions with solutes of varying solubilities and perform concentration calculations across multiple units.The simulation integrates a macroscopic visualization of the system, featuring realistic color changes and the appearance of undissolved solute upon exceeding solubility limits, alongside dynamic saturation graphs and solubility curves. Furthermore, it accounts for the critical distinction between solvent volume and final solution volume, incorporating non-additive volume effects. The environment includes formative assessment activities focused on concentration calculations, solubility equilibrium, and experimental decision-making for undergraduate General Chemistry.Finally, this development features a built-in language toggle (English/Spanish), enhancing its accessibility for international users. Additionally, its high-fidelity design makes it suitable for various educational strategies, such as pre-laboratory training, virtual labs, and flipped classroom models. Descripción Entorno virtual interactivo diseñado para la enseñanza de la preparación de disoluciones y el equilibrio de solubilidad. Este desarrollo corre en cualquier navegador moderno (de escritorio o móvil) y funciona tanto como laboratorio virtual como herramienta de pre-laboratorio, e incorpora instrumentación virtual realista, incluyendo un agitador magnético con control preciso de velocidad y temperatura. Permite a los estudiantes explorar la relación entre variables cinéticas, como la agitación, y las restricciones termodinámicas asociadas a la saturación y el equilibrio. Los usuarios pueden practicar la preparación de soluciones con solutos de diversa solubilidad y realizar cálculos de concentración en distintas unidades. La simulación integra una visualización macroscópica del sistema en un vaso de precipitados, con cambios de color realistas y la aparición de soluto no disuelto al superar los límites de solubilidad, junto con gráficos dinámicos de saturación y curvas de solubilidad. Además, contempla la distinción crítica entre el volumen de solvente y el volumen final de la disolución, incorporando efectos de no aditividad de volúmenes. El entorno incluye actividades de evaluación formativa orientadas al cálculo de concentraciones, al equilibrio de solubilidad y a la toma de decisiones experimentales para Química General universitaria. Finalmente, este desarrollo cuenta con un selector de idioma integrado (Inglés/Español), lo que mejora su accesibilidad para usuarios internacionales. Asimismo, su diseño de alta fidelidad lo hace apto para diversas estrategias educativas, tales como prácticas de pre-laboratorio, laboratorios virtuales y modelos de aula invertida.
