Electrons flow from the negative electrode (cathode) to the positive electrode (anode) in an electrolytic cell. This is the opposite direction of conventional current flow.

What is the significance of anode polarity in electrochemistry?

The significance of anode polarity in electrochemistry is that it determines the direction of electron flow in a galvanic cell or electrolytic cell. The anode is where oxidation occurs, and it is positively charged in a galvanic cell and negatively charged in an electrolytic cell. This polarity affects the overall reaction and the flow of ions in the cell.


In which cell does a current drive a nonspontaneous redox reaction?

A nonspontaneous redox reaction is driven by an external source of electrical energy, such as a battery, when a current passes through the electrolytic cell. In an electrolytic cell, the anode is positive and the cathode is negative; electrons flow from the anode to the cathode, and oxidation occurs at the anode while reduction occurs at the cathode.


What happen when zinc and copper in salt water?

When zinc and copper are placed in salt water, an electrolytic cell is formed. The zinc will undergo oxidation at the anode, releasing electrons into the circuit. These electrons flow to the copper electrode (cathode), where reduction occurs. This flow of electrons generates an electric current.


Why flow of current from cathode to anode still the flow of electrons is from cathode to anode?

The direction of current, according to convention, is the direction opposite the direction of electron flow. Remember that the anode is where oxidation occurs, so electrons are lost by the anode. These electrons then move from the anode, to the cathode by a wire that usually connects the two compartments. To reiterate, the electrons flow from the anode (site of oxidation) to the cathode (site of reduction). Because electrons flow from anode to cathode, by convention the direction of current is from cathode to anode (the direction opposite the flow of electrons). Hope this helps!


What is the role of the electrolytic cell anode and cathode in the process of electrolysis?

In electrolysis, the anode is where oxidation occurs, releasing electrons, while the cathode is where reduction occurs, accepting electrons. This process allows for the flow of electric current through the electrolyte, leading to the separation of ions and the chemical reactions that take place.

In the electrolytic cell electron flows from?

In the electrolytic cell, electrons flow from the negative terminal (cathode) to the positive terminal (anode). This flow allows for the oxidation of ions at the anode and the reduction of ions at the cathode, resulting in the desired chemical reactions to occur.

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.

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.


Do galvanometer has positive or negative terminals?

Absolutely not. The reason behind is that it shows currents (both ac and dc) which has a desired direction of flow of electrons.. So Galvanometer does not have any electrolytic terminals!!

Why do electrons only travel in one direction in voltaic cells?

The electrode potential or the reduction potential of zinc is less than that of copper. Therefore, zinc loses the electrons and copper ions gain them forming solid copper and producing electricity. Copper is not able to loose electrons due to presence of zinc and hence electrons flow in one direction only.


What gives electrons there electricity?

Electrons don't have electricity they only posses energy, Electricity is defined as the flow of electrons! In conductors the flow of valence electrons are called Electricity! therefore inducing a current in it! generally the direction of flow the current is the opposite of the direction of flow of electrons(D.C)!


What is the direction of current due to flow of electrons if it is not conventional current?

The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.
