Analysis of a galvanic cell

SCH4U U5L1 ANALYSIS OF A GALVANIC CELL GRADE – 4 % 24 marks EXPECTATIONS F2.4 build a galvanic cell and measure its cell potential. F2.5 analyse the processes in galvanic cells, and draw labelled diagrams of these cells to show the oxidation or reduction reaction that occurs in each of the half-cells, the direction of electron flow, the electrode polarity (anode and cathode), the cell potential, and the direction of ion movement. F3.2 identify the components of a galvanic cell, and explain how each component functions in a redox reaction F3.3 describe galvanic cells in terms of oxidation and reduction half-cells whose voltages can be used to determine overall cell potential INSTRUCTIONS 1. In this task, you will be analysing a galvanic cell. 2. Read page 695 to 700 in your textbook. 3. Research Galvanic cells from the picture on the next page or the link https://javalab.org/en/chemical_cell_en/ 4. Describe the  Parts/components of a galvanic cell  Way that each part functions in a redox reaction  concept/meaning/use of oxidation and reduction half cells  process that happens in a galvanic cell in simple language in a short paragraph of 4 – 6 lines. 5. Draw labelled diagrams of the half cells on your own to show:  oxidation or reduction reaction that occurs in each of the half-cells  the direction of electron flow  the electrode polarity (anode and cathode)  the cell potential  and the direction of ion movement SCH4U U5L1 The rubric is given below Categories KNOWLEDGE AND UNDERSTANDING Understanding of content – Understands the various components, processes and concepts of a galvanic cell.
