List the electrochemical series you developed from this lab based on the experimental values you obtained

Chemistry Jan 16, 2021

List the electrochemical series you developed from this lab based on the experimental values you obtained. Compare this to a published electrochemical series list, like the one in your eScience lab manual. Is yours different? If so, in what way is it different?Metal | Al (Trial 1) 2.5 g Al (Trial 2) Zn (Trial 1) Filter Paper Mass (9) Filter paper + Cu Mass (g) Cu Mass (g) Avg.

Expert Solution

The electrochemical series is the same as a published list since the electrode potential values are specific to the elements and do not change with reaction conditions.
