WebNov 13, 2024 ยท Section 1 - Dissolving and Concentration. The activity begins with a short video (video 1) that introduces the dissolving process. This video explains how certain substances dissolve in water, defining terms like solute, solvent, and solution. Additionally, students learn and practice calculating the molar concentration of a solution. WebActivity is defined as a measure of the effective concentration of a molecule or ionic species. Activity depends on the temperature, pressure and composition of the mixture of species. Activity of a solute depends on its concentration, being proportional to concentration at sufficient dilution.
