What else can I help you with?
Is the cathode or anode positive in a galvanic cell?
In a galvanic cell, the cathode is positive.
Is the cathode positive or negative in a galvanic cell?
In a galvanic cell, the cathode is the positive electrode.
What would be the cathode in a magnesium and zinc galvanic cell?
The magnesium would be the cathode in a galvanic cell with zinc. Reduction occurs at the cathode during cell operation, and in this case, magnesium is reduced while zinc undergoes oxidation at the anode.
Is the anode positive in a galvanic cell?
Yes, the anode is positive in a galvanic cell.
Which component, the anode or cathode, is more prone to corrosion in a galvanic cell?
The anode is more prone to corrosion in a galvanic cell.
Is the cathode or anode positive in a galvanic cell?
In a galvanic cell, the cathode is positive.
Is the cathode positive or negative in a galvanic cell?
In a galvanic cell, the cathode is the positive electrode.

Is the anode positive in a galvanic cell?
Yes, the anode is positive in a galvanic cell.
Which component, the anode or cathode, is more prone to corrosion in a galvanic cell?
The anode is more prone to corrosion in a galvanic cell.
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.
How is an electrolytic cell different from a glavantic cell?
An electrolytic cell uses electrical energy to drive a non-spontaneous chemical reaction, typically involving the decomposition of compounds, while a galvanic (or voltaic) cell generates electrical energy from spontaneous chemical reactions. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a galvanic cell, the anode is negative and the cathode is positive. Additionally, electrolytic cells require an external power source, while galvanic cells operate independently by harnessing the energy from chemical reactions.
How is an electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.
What is the cathode of a galvanic cell made with magnesium and gold?
the gold electrode
Is the anode positive or negative in a galvanic cell?
In a galvanic cell, the anode is the negative electrode.
What occurs at the cathode of the galvanic cell?
The reduction half-reaction of a redox reaction
Electrons in a galvanic cell normally flow?
A galvanic cell is a spontaneous reaction so electron flow will occur as long as a salt bridge is present.
