What is the relationship between the cathode and anode in an electrochemical cell?
In an electrochemical cell, the cathode is where reduction occurs, while the anode is where oxidation occurs. The cathode and anode are connected by an external circuit, allowing for the flow of electrons from the anode to the cathode. This flow of electrons generates an electric current in the cell.
What is the relationship between the ecathode and eanode in an electrochemical cell?
In an electrochemical cell, the cathode is where reduction occurs, while the anode is where oxidation occurs. The cathode and anode are connected by an external circuit, allowing the flow of electrons from the anode to the cathode. This flow of electrons generates an electric current in the cell.
Why is the cathode negative in an electrochemical cell?
In an electrochemical cell, the cathode is negative because it attracts positively charged ions from the electrolyte solution, allowing for the flow of electrons and the generation of electrical current.
What is the role of the negative cathode in an electrochemical cell?
The negative cathode in an electrochemical cell is where reduction reactions occur. It attracts positively charged ions from the electrolyte, allowing electrons to flow through the external circuit to the positive anode. This flow of electrons generates electrical energy in the cell.
What is the difference between anode and cathode in terms of their functions in an electrochemical cell?
In an electrochemical cell, the anode is where oxidation occurs, releasing electrons. The cathode is where reduction occurs, accepting electrons. This creates a flow of electrons from the anode to the cathode, generating electrical energy.
Why cathode is positive in electrochemical cell but different in electrolytic cell?
In an electrochemical cell (galvanic cell), the cathode is positive because it is where reduction occurs, attracting cations from the electrolyte. Conversely, in an electrolytic cell, the cathode is negative because it is connected to the external power source, which forces electrons into the electrode, facilitating reduction at that terminal. Thus, the polarity of the cathode changes depending on the type of cell and the direction of the current flow.
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 the relationship between the cathode and anode in an electrochemical cell?
In an electrochemical cell, the cathode is where reduction occurs, while the anode is where oxidation occurs. The cathode and anode are connected by an external circuit, allowing for the flow of electrons from the anode to the cathode. This flow of electrons generates an electric current in the cell.

Why is the cathode negative in an electrochemical cell?
In an electrochemical cell, the cathode is negative because it attracts positively charged ions from the electrolyte solution, allowing for the flow of electrons and the generation of electrical current.
The anode in an electrochemical cell has this charge?
The Anode in electrochemical cell has negative charge (-ve).
What is the role of the negative cathode in an electrochemical cell?
The negative cathode in an electrochemical cell is where reduction reactions occur. It attracts positively charged ions from the electrolyte, allowing electrons to flow through the external circuit to the positive anode. This flow of electrons generates electrical energy in the cell.
What is the difference between anode and cathode in terms of their functions in an electrochemical cell?
In an electrochemical cell, the anode is where oxidation occurs, releasing electrons. The cathode is where reduction occurs, accepting electrons. This creates a flow of electrons from the anode to the cathode, generating electrical energy.
What are the names of the 2 electrodes in an electrochemical cell?
In an electrochemical cell, the two electrodes are called the anode and the cathode. The anode is where oxidation occurs, leading to the release of electrons, while the cathode is where reduction takes place, accepting those electrons. The flow of electrons from the anode to the cathode generates electric current.
A simple electrochemical cell contains two electrodes?
In a simple electrochemical cell with two electrodes, one electrode acts as the anode (where oxidation occurs) and the other as the cathode (where reduction occurs). When the cell is connected in an external circuit, ions flow from the anode to the cathode, releasing electrons at the anode and accepting them at the cathode to complete the redox reaction.
Where do the electrons enter an electrochemical cell?
Electrons enter an electrochemical cell through the anode. The anode is where oxidation occurs, leading to the release of electrons that flow through the external circuit to the cathode.
In an electrochemical cell where are electrons produced?
Electrons are produced at the anode of the electrochemical cell during the oxidation half-reaction. As the anode oxidizes, it releases electrons that flow through the external circuit to the cathode.
