Galvanic Cells practical (1 Viewer)

[mathgenius]

For the galvanic cells prac, are there any other contributing factors other than standard conditions to not getting the theoretical voltage value? Also, any pointers on reliability? Thanks in advance

We did it and all of our values were super low (I think 0.8V was the highest). It could have been having less contact between the metals and electrolytes or metals and voltmeter clips, or a dodgy voltmeter, or our salt bridges (filter paper soaked in a third electrolyte) only just touched the main electrolytes. But the outputs of each cell in relation to each other were the same as the order in the theoretical values, which was satisfying. For reliability repetition is the main thing you can always fall back on.
