Need help answering the following questions to be able to write up a prac report - thanks;
RESULTS;
Metal combination and volatge
Fe + Cu = 0.58
Fe + Mg = -1.14
Fe + Zn = - 0.43
Cu + Mg = -1.71
Cu + Zn = - 1.02
Mg + Zn = 0.66
Questions;
1) Which metals in combnation created the highest volatge?
2) Relate your results to the position of each metal in the reactivity series.
3) In the zinc/copper cell, in which direction is the electric current flowing?
4) Silver is less reactive than copper. If connected to a magnesium half cell would the voltage created be larger or smaller than a Cu/Mg cell? Explain.
