What else can I help you with?
Is the cathode positive in a galvanic cell?
No, the cathode is negative in a galvanic cell.
Is the cathode or anode positive in a galvanic cell?
In a galvanic cell, the cathode is positive.
Is the anode positive or negative in a galvanic cell?
In a galvanic cell, the anode is the negative 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 negative in a galvanic cell?
Yes, the anode is negative in a galvanic cell.
Is the cathode positive in a galvanic cell?
No, the cathode is negative in a galvanic cell.
Is the cathode or anode positive in a galvanic cell?
In a galvanic cell, the cathode is positive.
Is the anode positive or negative in a galvanic cell?
In a galvanic cell, the anode is the negative electrode.
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.
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 galvanic cell?
Electrons flow in the opposite direction.
I don't understand. What are anodes and cathodes Positive or Negative I keep seeing different answers everywhere Thanks.?
It can be complicated depending on the type of cell one is looking at. However, here is my simple explanation.The anode is the electrode where the oxidation reaction takes place, and oxidation is the loss of electrons, so in a galvanic cell the anode is a source of free electrons and so it is negatively charged.The cathode is the electrode where reduction takes place, and reduction is the gain of electrons, so in a galvanic cell the cathode is positively charge and ready to accept negatively charged electrons.Now, the anode isn't always negative and the cathode isn't always positive. It has to do with the direction of current flow (anode = current in, cathode = current out). In an electrolytic cell, the charges on the anode and the cathode are reversed from that seen in a galvanic cell.
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 negative in a galvanic cell?
Yes, the anode is negative in a galvanic cell.
Name of one electrode and say is positive or negative?
The Cathode is the negative electrode; the anode 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.
