Base electrochemistry is a prerequisite of the module 1 that you must complete before taking corrosion properties of bulk materials.
In this activity you will repeat or re-learn theory and practice of base electrochemistry (theoretical knowledge on a galvanic cell).
For a good results of the activity, please, read the text
and see the video
Look at each of these task and answer the questions
Then read the feedback. Use the table of standard ELECTRODE POTENTIAL
Silver is cathode in Ni-Ag galvanic cell. True or false?
Note the metals that can be used as anode in galvanic cell with Co-cathode
Choose the single correct or the single incorrect statement
Choose some correct and some incorrect points for the galvanic cell were Ag-electrode is immersed into an aqueous solution of silver nitrate and Pb-electrode is immersed into an aqueous solution of lead nitrate (anode)Pb|Pb(2+)||Ag(+)|Ag(cathode) (anode)Ag|Ag(+)||Pb(2+)|Pb(cathode) Pb-2e=Pb(2+) Pb(2+)+2e=Pb
For a good results of the activity, please, read the text Basics of Electrochemistry and see the video presented in Activity 1
Look at each of these task, make the calculation and chose one correct answer Then read the feedback. Use the table of standard electrode potentials
Find the standard potential of the cell Sn(s)|Sn(2+)|| Cu(2+)|Cu(s)
Find the standard potential of the cell Zn(s) | Zn(2+) || Pb(2+) | Pb(s)
Specify an equation that allows us to calculate the standard electrode potential
