• Electrolysis is the decomposition of a compound into its elements by an electric current; usually carried out in an electrolysis cell: • In the electrolysis cell:  The electrolyte is the compound being decomposed, either molten ionic compound or a concentrated aqueous solution of ions  The electrodes are rods, made from carbon or metal, which conducts electricity to and from the electrolyte:  Anode: positive electrode (oxidation)  Cathode: negative electrode (reduction...

What is a junction potential? - correct answers When dissimilar electrolyte solutions are in contact, a voltage difference, called a junction potential, will usually develop at their interface. What is a fundamental limitation on the accuracy of direct potentiometric measurements? Why? - correct answers Junction potential; we do not know its contribution to voltage What is alkaline error when using a pH measuring glass electrode? - correct answers Too much Na+ relative to H+, electrode wil...
