Penny Battery Flashcard

The anode is the electrode where oxidation occurs in a battery, typically made of a material like zinc.

To oxidize means to remove electrons from an element, often resulting in a change in its chemical state.

An ion is an atom or molecule that has an unequal number of protons and electrons, resulting in a net electrical charge.

In a penny battery, electrons move from the anode (zinc) to the cathode (copper wire).

The electrolyte facilitates the movement of ions and is responsible for producing electricity in a battery.

The cathode is the electrode where reduction occurs in a battery, typically made of a material like copper.

At the anode, zinc oxidizes, releasing electrons and forming zinc ions.

At the cathode, copper ions gain electrons and are reduced to form solid copper.

Lemon juice acts as an electrolyte, allowing ions to move between the electrodes.

Hydrogen gas can be produced during the electrochemical reactions in a battery, indicating a chemical change.
