ELECTROCHEMISTRY

BASIC BATTERY SET UP

ELECTROCHEMISTRY

• The study of electricity
• How it relates to chemical reactions
• Can be generated by movements of electrons

REAL LIFE EXAMPLES

• Wet cell batteries contained in a liquid and have more power; is used in cars
• Dry cell batteries are electrolytes containing in a low moisture paste.They are used in households.

CORROSION

• process in which a solid, esp a metal, is eaten away and changed by a chemical action, It can block the charge from the battery to the system if there is to much.
• as in the oxidation of iron in the presence of water by an electrolytic process.
• The corrosion gets between the terminals and the power won't go through.

ELECTROLYSIS

• a method of using a direct electric current to drive an otherwise non-spontaneous chemical reaction. -
• Can be used for coating artificial jewelery with gold to give it an attractive look .

OXIDATION REDUCTION IN BATTERIES

• . They have to appear together in a chemical reaction.
• For a battery to work, both an oxidation and a reduction must happen. One generates electrons at one electrode, and the other uses them up at the other electrode.
• Oxidation and reduction reactions cannot be carried out separately
