Planning and conducting
Elaboration
- Sample opportunities to support student inquiry:
- Determine the rate of a reaction through experimentation.
- Identify an unknown ion through experimentation involving a qualitative analysis scheme.
- Devise a method for determining the concentration of a specific ion by titration or gravimetric methods (e.g., concentration of chloride ion using a precipitation reaction with silver ion).
- Design, perform, and analyze a titration experiment involving:
- primary standards
- standardized solutions
- titration curves
- appropriate indicators
- proper technique
- Prepare a buffer system.
- From data for a series of simple redox reactions, create a simple table of reduction half-reactions.
- Construct an electrochemical cell. Determine the half-reactions that take place at each electrode, the overall reaction, and the resulting mass of the electrodes.
- Design and label the parts of an electrolytic cell:
- used for the electrolysis of a molten binary salt (e.g., NaCl(l))
- capable of electrolyzing an aqueous salt (e.g., KI(aq), not requiring the use of overpotential effect)
- used to electroplate an object
