Societal Implications and Applications

•D1.1 analyse processes in the home, the workplace,and the environmental sector that involve the use of chemical quantities and calculations (e.g., mixing household cleaning solutions,calculating chemotherapy doses, monitoring pollen counts)

•For this section, students can do a case study and cover topics such as the following to go GREEN:

•

Making your own cleaning supplies

•Recycle Electronics and Impacts of electronics on environment

•Green your closet

•Remember the 3 R’s (reduce, reuse, recylce)

•D1.2 assess, on the basis of research, the importance of quantitative accuracy in industrial chemical processes and the potential impact on the environment if quantitative accuracy is not observed [IP, PR, AI, C]

•For this section, students can do a lab to explore effects of a chemical on a surface.

•salicylic acid and ASA- have different properties.

•Materials: 1 scoop ASA, 1 scoop Salicylic acid, water, two beakers, dropper, Al foil

•Safety precautions: protective clothing, gloves and goggles.

•Consolidation: Describe the effects of each chemical on each surface?

•What can you conclude about the corrosiveness of acetylsalicylic acid and salicylic acid?

Societal Implications and Applications Cont'd

• Chemists use the mole to count very small particles, such as atoms, molecules, ions,and formula units.
• Conversion factors, such as molar mass and the Avogadro constant, allow chemists to convert among number of particles, moles and mass. A
• An important aspect of industrial chemical processes is the need for quantitative accuracy. There can be many potential environmental impacts if accuracy is not observed.
