电化学英语
Electrochemistry is a branch of chemistry that deals with the study of chemical reactions that involve the transfer of electrons between reactants. It involves the understanding of how electricity can be generated or harnessed through chemical reactions.
Here are some common terms and phrases used in electrochemistry:
reaction between pvp and amino
1. Electrode: A conductive material that allows the transfer of electrons between the reaction and an external circuit.
2. Electrolyte: A substance that conducts electric current when dissolved in a solvent.
3. Galvanic cell: An electrochemical cell that converts chemical energy into electrical energy through spontaneous redox reactions.
4. Electrolysis: A process in which an electric current is passed through an electrolyte to drive a non-spontaneous redox reaction.
5. Redox reaction: A chemical reaction in which there is a transfer of electrons from one species (reducing agent) to another (oxidizing agent).
6. Cathode: The electrode where reduction (gain of electrons) occurs.
7. Anode: The electrode where oxidation (loss of electrons) occurs.
8. Cell potential: The difference in potential energy between the electrodes in an electrochemical cell, measured in volts.
9. Faraday's Law: The amount of substance involved in an electrochemical reaction is directly proportional to the quantity of electricity passed through the cell.
10. Ohm's Law: The current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor.
These are just a few examples of terms and phrases commonly encountered in the field of electrochemistry.
