QuestionAnswer
Define a cathodeThe electrode where reduction (gain of electrons) occurs during an electrochemical reaction.
Define an anodeThe electrode where oxidation occurs during an electrochemical reaction, attracting positively charged ions or electrons.
Explain how two half-cells can be connected by a salt bridge to create a voltaic cell.Two half-cells can be connected by a salt bridge to create a voltaic cell, allowing the flow of ions between the half-cells to maintain charge neutrality and facilitate the redox reactions that generate electrical energy.
How to determine the strength of oxidising and reducing agents?Comparing their standard electrode potentials.
