Using the Factors Affecting Solubility Chemistry Guided-Inquiry Kit, students investigate the effects of stirring, temperature, surface area and the amount of solute already dissolved in solution on the rate of dissolving.
Why is it that some solids take so much longer to dissolve than others? What factors affect the rate at which a solute dissolves in solution? In this laboratory activity, students will investigate the effects of stirring, temperature, surface area and the amount of solute already dissolved in solution on the rate of dissolving. This activity works well as an open-ended, inquiry-based lab, but may also be performed as a standard laboratory activity—instructions are included for both formats. Includes reproducible student handouts, background information and complete Teacher Notes with sample data and answers to questions, plus all chemicals needed to perform the lab.
Complete for 30 students working in pairs.
