Year 12 CHEMISTRY TERM 1PLANNER Unit 5: REDOX -Metal Extraction

Section / GOALS and SUCCESS CRITERIA / Reference / Done!
SC1 / Recall patterns of electron configuration, ionisation energy, and electronegativity within the periodic table.
SC2 / Recall the basic periodic properties of metals versus non-metals, and identify elements into either group on the basic of these properties
1 4lessons / SC3 / Recall the basic chemistry (ie. Electron exchange and formation of compounds) of metals versus non-metals
SC4 / Explain how periodic properties influence the chemistry of different metals
SC5 / Describe the discovery, extraction, and use of metals such as Gold and Iron, and contrast with the discovery of metals such as Calcium and Sodium
LG1 / Justify a metals discovery and its uses using the concepts of electron configuration, ionisation energy and/or electronegativity (ie. relative reactivity - likeliness to oxidise and/or reduce)
SC6 / Measure relative reactivity of metals and construct an activity series
SC7 / Define the terms Oxidation, Reduction, REDOX reaction, reductant, oxidant)
2 / SC8 / Assign Oxidation Numbers
4 lessons / SC9 / Identify REDOX reactions, oxidants, and reductants using Oxidation numbers
SC10 / Balance REDOX equations using Oxidation numbers
LG2 / Within a simple chemical scenario identifyand explain any REDOX chemistry and Oxidant and Reductant
SC11 / Recognise the potential to create “external” electron flow from substances which differ significantly in their electronegativity – making a “battery”.
SC12 / Define Galvanic cells, Anode, Cathode, Salt bridge, electrolyte, and Battery.
3 / SC13 / Construct a range of Galvanic cells and measure cell voltage.
6lessons / SC14 / Define Standard Reduction Potential (SRP), and know the conditions of its measurement.
SC15 / Use a table of SRP’s to identify the oxidant, reductant, EMF (cell potential/voltage), Anode, Cathode, direction of electron flow, and direction of ion flow in a given Galvanic cell.
LG3 / Use a table of SRPto determine the Voltage produced by a Galvanic cell under a range of conditions (concentration), and be able to design a galvanic cell given a voltage requirement and conditions (materials and concentration available)
SC16 / Define Electrolytic cell.
SC17 / Use a table of SRP’s to identify an Electrolytic cell; and identify the Anode, Cathode, direction of electron flow, and direction of ion flow in a given Electrolytic cell.
4 / SC18 / Use a table of SRP’s to identify the possible Oxidants and Reductants in an Electrolytic cell.
4 lessons / SC19 / Use a table of SRP’s to identify the preferred oxidant and reductant given an electrolytic cell and its conditions (concentration and voltage).
SC20 / Construct an electrolytic cell to perform a specific function (anodise Al, or “shine” Ag)
LG4 / Design and/or justify the use an Electrolytic cell (and voltage) to perform a specific function, given materials and conditions (concentration)
SC21 / Recognise the extraction of metals from their ores is a redox reaction in which the metal ion acts as an oxidant.
SC22 / Extract Copper from an ore using the 3 stage process of Copper Leach Extraction
SC23 / Relate the position of a metal on the table of SRP’s, or the Activity series to its relative ease of extraction from its ore/mineral.
5 / SC24 / Determine concentrations of copper ions from leach solutions using spectroscopy
10 lessons / SC23 / Know the four generic redox processes for metal extraction from ores/minerals – and the relative advantages and/or disadvantages of each.
LG5 / Predict and/orJustify the generic method of extraction for any metal found on the table of SRP’s or Activity series AND specific variations from the generic method for a given metal or mineral
LG6 / Explain and Justify the chemical and/or economic application of the leaching process on low grade copper ores.
