Study Notes
Redox Equations
- The half-reaction method is commonly used to balance redox equations by separating oxidation and reduction processes.
Reducing Agent
- A reducing agent serves to donate electrons in a redox reaction, facilitating the reduction of another substance while itself getting oxidized.
Electrolytic Cell
- In an electrolytic cell, external electric energy drives non-spontaneous reactions, allowing the conversion of electrical energy into chemical energy.
Cell Types
- Galvanic (or voltaic) cells convert chemical energy into electrical energy, providing power through spontaneous reactions.
Metal Corrosion
- The key process related to metal corrosion involves oxidation reactions leading to the deterioration of metals when they react with environmental factors.
Ion Movement in Electrochemical Cells
- The salt bridge in an electrochemical cell allows ions to move between the two half-cells, maintaining charge balance and enabling continuous flow of current.
