Where does oxidation take place in an electrochemical cell?
Oxidation takes place at the anode in an electrochemical cell.
Why is the chlorine ion oxidised when it reacts at the negative electrode?
Chlorine ion is oxidized at the negative electrode because it gains electrons, which is the process of oxidation. In this case, the chlorine ion loses its extra electron to become a chlorine atom, which is an oxidation process.
What is the relationship between the working electrode and counter electrode in electrochemical reactions?
In electrochemical reactions, the working electrode and counter electrode are two essential components that work together. The working electrode is where the chemical reaction takes place, while the counter electrode completes the circuit and balances the charge. They are connected through an electrolyte solution, allowing the flow of ions to facilitate the reaction. The working electrode drives the reaction, while the counter electrode ensures that the overall charge remains balanced.
What does the term anodic mean?
The term "anodic" refers to the electrode or region in an electrochemical cell where oxidation occurs. In simple terms, it is the positively charged electrode where electrons are released.
Why hydrogen is used as a standard electrode?
Hydrogen is used as a standard electrode because it has a well-defined standard electrode potential and is easily reversible in its oxidation and reduction reactions. This makes it a reliable reference point for measuring the electrode potentials of other half-reactions in electrochemical cells.
What is an oxidising electrode?
according to me anode should be oxidizing electrode as oxidation reaction takes place on anode
Which is the electrode is the anode in a galvanic cell?
The electrode with the highest oxidation potential
Where does oxidation take place in an electrochemical cell?
Oxidation takes place at the anode in an electrochemical cell.
Why oxidation takes place at anode and reduction takes place at cathode?
Oxidation occurs at the anode because it is the electrode where the loss of electrons happens, leading to an increase in oxidation state of the species involved. Conversely, reduction occurs at the cathode as this is the site where electrons are gained, resulting in a decrease in oxidation state. This separation of processes is fundamental to electrochemical cells, where the flow of electrons from the anode to the cathode drives the overall chemical reactions. Thus, the anode and cathode serve distinct roles in facilitating oxidation and reduction, respectively.
What is an hydrogen electrode?
The standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials.
At which electrode does reduction take place in a fuel cell?
In a fuel cell, reduction takes place at the cathode. This is where oxidants, such as oxygen, gain electrons that have traveled through the external circuit from the anode, where oxidation occurs. The reduction process at the cathode is essential for generating electrical energy in the fuel cell.
What kind of oxidation takes place when oxygen and glucose combine?
It is called aerobic respiration, oxidation is usage of oxygen .
What electrode get heavier in an electrolytic cell?
In an electrolytic cell, the cathode is the electrode that gets heavier. This occurs because reduction reactions take place at the cathode, where cations from the electrolyte gain electrons and deposit onto the electrode, increasing its mass. Conversely, at the anode, oxidation reactions cause the electrode to lose mass as material is oxidized and released into the solution.
Can oxidation or reduction takes place alone why or why not what are such reactions called answer in chemistry?
These reactions are called redox reactions.Isolated reduction/oxidation is not possible.
Which chemical reaction takes place while smoking?
Oxidation (slow burning of the tobacco)
What are the substances released when oxidation takes place in the cell?
water, carbon dioxide and oxygen
What occurs at the cathode of a galvanic cell?
An oxidation half-reaction
