SCH 4U - Electrolysis





Homework: #30-37


Success Criteria

- be able to determine the oxidation number of an element in a compound or a polyatomic ion.

- be able to define oxidation, reduction, half-reaction, redox reaction, spectator ion, inert electrode, cell, battery, primary/secondary cell, corrosion, sacrificial anode, cathodic protection, electrolysis, etc.

- be able to write out (i) total ionic equation, (ii) net ionic equation, (iii) balanced oxidation half-reaction (iv) balanced reduction half reaction for a redox reaction, (v) provide Eox & Ered, (vi) calculate Ecell and (vii) determine/explain if a cell reaction is spontaneous

- be able to balance a redox reaction equation (in acidic or basic solution) using the ion-electron &/or the oxidation number method

- be able to draw a fully labelled galvanic cell from a shorthand notation representing the cell and vice versa

- be able to choose the best/worst oxidizing/reducing agent from a list using E values 

- be able to answer multiple choice questions based on the "Cells and Batteries" and "Corrosion" reading

- be able to interpret an electrolytic cell (as in the lesson), with an emphasis on determining the minimum required voltage
