CHEM.11.C
The student is expected to investigate how solid and gas solubilities are influenced by temperature using solubility curves and how rates of dissolution are influenced by temperature, agitation, and surface area;
Knowledge and Skills Statement
Science concepts. The student understands and can apply the factors that influence the behavior of solutions.

Summary: An integrated study was conducted on the effects of temperature and pH on the solubility of whey proteins. The solubility was determined experimentally in the temperature range of 40-90 °C, and pH range of 5.0 - 6.8. The results showed that both the temperature and pH influenced protein solubility. It was also observed that solubility decreased when temperature increased.

Summary: In the general chemistry curriculum, kinetics--the study of the rates of reactions--is often approached in a classical and somewhat mechanical sense (Zumdahl 2009; Tro 2011) This article presents a hands-on activity to help address these issues and promote real understanding of kinetics.
