A galvanic cell is a spontaneous reaction so electron flow will occur as long as a salt bridge is present.

How is an electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.
Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
How is an electolytic cell different from a galvantic cell?
electrons flow in the opposite direction
How current flow from positive to negative terminal in cell?
DC current. Some experts argue that indications show that electrons flow from negative to positive (According to current arguments), but it is assumed generally that electrons flow from positive to negative.
How is discharging in a positive object different in a negative object?
The direction of the flow of electric current. In a positive object, electrons flow to it because it has an abscence of negative charge (aka electrons). In a negative object, it has an abundance of negative charge (electrons) so electrons flow away from it.
How is a electrolytic cell different from galvanic cell?
Electrons flow in the opposite direction.
How is electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.
How does a galvanic cell work?
.. A redox reaction at two electrodes causes electrons to 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 allows electrons to flow between electrodes in an electrochemical cell?
The difference in reactivity between two metals is what causes the electron flow, or voltage. It is facilitated by setting up a Galvanic cell, with two electrodes in solution connected by a copper wire (for electron flow) and a salt bridge (for balancing charges between electrodes.)
Is current a flow of electrons?
In general, yes, we normally think of the movement of electrons (electron flow) as electric current.
What is the role of electrons in a voltaic cell?
a volcanic cell has electrodes and electrons flow through electrodes .
In which direction do electrons flow?
From anode to cathode.
What is oxidized in a galvanic cell?
The anode
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.
Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
