Electrochemistry is the branch of chemistry that studies the relationship between electricity and chemical reactions.
It focuses on how:
- Chemical reactions can produce electricity (as in batteries or voltaic cells).
- Electricity can drive chemical reactions (as in electrolysis).
In simple terms, electrochemistry explains:
- How electrons move during chemical reactions.
- How chemical energy can be converted into electrical energy.
- How electrical energy can be used to cause chemical changes.
Applications include batteries, fuel cells, electroplating, corrosion prevention, and sensors.
It essentially connects the worlds of chemistry and electricity.
