Question

What are the possible source of errors in electrolytes lab?

Answer 1

possible source of errors in electrolytes lab

purity of chemicals

concentration

temperature

voltage drops are the actual electrical resistances in the "circuits", the cells themselves".

every circuit has some resistance, and the affect of the resistance is to lower the potential difference, the voltage of the cell.

internal resistance: which can minimize it by using "clean" electrodes and keeping the distances between electrodes short.

an error in your voltmeter.
