If the reactants in a galvanic cell are in contact?
If the reactants in a galvanic cell are in contact, electrons will flow from the anode (where oxidation occurs) to the cathode (where reduction occurs) through the external circuit. This flow of electrons creates an electric current that can be used to do work.
What characterizes a galvanic cells?
A galvanic cell consists of two half-cells connected by a salt bridge, allowing the flow of ions between them. One half-cell undergoes oxidation (loses electrons) and the other undergoes reduction (gains electrons), leading to the flow of electrons through an external circuit. This flow of electrons generates an electric current that can be used as a source of power.
What is standard cell notion of a galvanic cell made with zinc and aluminum?
In a standard galvanic cell using zinc and aluminum, the zinc metal will act as the anode and the aluminum metal will act as the cathode. Zinc will undergo oxidation at the anode, releasing electrons which flow through the external circuit to the cathode where aluminum will undergo reduction. This flow of electrons creates an electrical current.
How is an electolytic cell different from a galvantic cell?
In an electrolytic cell, electrical energy is used to drive a non-spontaneous reaction, causing a chemical change. In contrast, a galvanic cell generates electrical energy from a spontaneous chemical reaction. Electrolytic cells are often used in processes like electrolysis, while galvanic cells are used in batteries.
How is an electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.

What is oxidized in a galvanic cell made with silver and nickel electrolodes?
In a galvanic cell with silver and nickel electrodes, nickel is oxidized at the anode. During oxidation, nickel atoms lose electrons and become Ni2+ ions, contributing to the flow of electrons in the cell. Silver acts as the cathode where reduction reactions take place.
What is oxidized in galvanic cell made with silver and nickel electrodes?
In a galvanic cell made with silver and nickel electrodes, the nickel electrode undergoes oxidation as it loses electrons, which travel through the external circuit to the silver electrode where reduction occurs. This flow of electrons generates an electric current in the cell.
What is oxidized in a galvanic cell?
The anode
How does a galvanic cell work?
.. A redox reaction at two electrodes causes electrons to flow.
What prevents charge build up in galvanic cell?
A salt bridge

What is the function of a salt-bridge in an electrochemical cell?
The salt bridge allows cations to move in the galvanic cell. Electrons move from the anode to the cathode, leaving cations behind. The salt bridge allows for a balance of cations and anions to occur to continue the flow of electrons.
What is source of electrical energy in galvanic cell?
The source of electrical energy in a galvanic cell is the chemical reaction that takes place between the two half-cells. This reaction creates a flow of electrons from the oxidation half-reaction to the reduction half-reaction, generating an electric current. The movement of electrons through an external circuit is what produces the electrical energy.
