Difference between electrolysis and electrochemical cells?
In an electrochemical cell, electrons move spontaneously from anode to cathode. In electrolytic cell, energy has be applied to make electrons move in the circuit. Electrochemical cell are easy to create.
Does removing oxygen always prevent an oxidation recreation?
Removing oxygen does prevent oxidation from occurring since oxidation is a chemical reaction that involves the gain of oxygen by a substance. Without oxygen present, oxidation cannot take place.
What is the role of the working electrode in electrochemical reactions?
The working electrode in electrochemical reactions serves as the site where the desired chemical reactions take place. It is where electrons are either gained or lost, leading to the conversion of chemical substances into different forms. The working electrode plays a crucial role in determining the efficiency and outcome of the electrochemical process.
What is oxidized in a galvanic cell made with silver and nickel electrolodes?
In a galvanic cell with silver and nickel electrodes, nickel is oxidized at the anode. During oxidation, nickel atoms lose electrons and become Ni2+ ions, contributing to the flow of electrons in the cell. Silver acts as the cathode where reduction reactions take place.
Which process could the cell use to take in more sodium?
The cell could increase the activity of sodium-potassium pumps on the cell membrane to actively transport more sodium into the cell against its concentration gradient. Alternatively, the cell could increase the expression of sodium channels on the cell membrane to allow passive diffusion of sodium into the cell down its electrochemical gradient.
Oxidation takes place at anode and reduction at cathode?
In an electrochemical cell, oxidation occurs at the anode, where electrons are lost as a result of a redox reaction. The anode is where oxidation half-reactions take place, generating electrons that flow through the external circuit to the cathode. Reduction, on the other hand, occurs at the cathode, where electrons are gained during the redox reaction. This flow of electrons from anode to cathode is what generates an electric current in the cell.
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.
Where oxidation and reduction takes place?
Oxidation of water occurs wherever there is photosynthesis. Plants and organisms that perform photosynthesis take in water and other minerals and convert them to sugar, but the conversion to sugar creates a biproduct of free oxygen. This oxygen then oxidizes the water.
How is cellular respiration take place?
By oxidation of organic substrates
Why does cell respiration take place?
All living beings need energy to maintain there lives. Respiration is chemically oxidation of big molecules to release energy. This burning of fuel in a cell (or organism) is called respiration.
Does oxygen have to be present for an oxidation-reduction reaction to take place?
nope
Where does most of the cell's activities take place?
In the protoplasm within the cell membranes of organic and inorganic substances (water and protien) and structures that have specific functions. The most of the cellular activity takes place in the mitochondrion of the cell . mITOCHONDRION is called a power house of the cell this is the place were most of the ATP is produced and oxidation of the food molecules also takes place here. It is a double walled organelle .
When does replication in a cell take place?
replication in the cell take place in the second phase which is the metaphase.
Difference between electrolysis and electrochemical cells?
In an electrochemical cell, electrons move spontaneously from anode to cathode. In electrolytic cell, energy has be applied to make electrons move in the circuit. Electrochemical cell are easy to create.
Can the metal plates in an electrochemical cell be made of the same metal?
Historically, no, each metal has its own redox potential and it is the difference between them that causes the flow of electrons with the electrolyte carrying the charge in the cell and the circuit between the metals that carries them outside the cell. However, there are now cells that do not use the metals to create the electrochemical potentials where the metals are only conductors wherein the metals are where the electrochemical reactions take place, but are not reactants. These have to have a membrane between the two reaction compartments to keep the two reactants from reacting in solution or in the gaseous state. These are more often referred to as batteries in my opinion, or as fuel cells.
Does photosynthesis take place in the cell membrane?
no it takes place in a plant cell with no cell membrane but a cell wall
Why is it possible for both reduction and oxidation to take place at the same time?
There are chemical handbooks and journals filled with examples of oxidation reduction reactions.
