What is the purpose of the salt bridge in an electrochemical cell?
The purpose of the salt bridge in an electrochemical cell is to maintain electrical neutrality by allowing the flow of ions between the two half-cells, preventing the buildup of charge and enabling the continuous flow of electrons in the cell.
What are electrochemical impulses?
While a neural signal is chemically conveyed from one neuron to another by neurotransmitters, the electro-chemical neural impulse, which happens in the axon when the neuron fires, is called an action potential.
What is a combination of two or more electrochemical cells in series that store chemical energy which transforms into electrical energy?
A battery is a combination of two or more electrochemical cells in series that store chemical energy which transforms into electrical energy.
Does acidity affect voltage?
Acidity is the potential for Hydrogen ions in a solution Voltage is the electrical potential difference. These have nothing to do with each other per se. They can be involved in a battery or electrochemical reaction....
What is the study of the chemical effects of electrical action?
The study of the chemical effects of electrical action is called electrochemistry. This field focuses on the relationship between chemical reactions and electricity, including redox reactions and electrolysis. It has applications in batteries, corrosion prevention, and fuel cells.
What is the basic difference between solar cells and fuel cells?
A fuel cell is an electrochemical energy conversion device whiles a solar cell is a device that converts photons from the sun into electricity.
How does the electrochemical process help you?
The electrochemical process involves the conversion of chemical energy into electrical energy, making it useful for applications like batteries, fuel cells, and electrolysis. It provides a way to efficiently store and produce energy for various devices and systems.
Factors affecting emf of electrochemical cells?
temperature,length of the wire,area,potential difference
What is the Difference between electrochemical cell and fuel cell?
An electrochemical cell is a device that converts chemical energy into electrical energy through redox reactions, and it can function in both galvanic (battery) and electrolytic modes. A fuel cell, on the other hand, is a specific type of electrochemical cell that continuously converts the chemical energy of a fuel (usually hydrogen) and an oxidant (like oxygen) into electricity, water, and heat, as long as fuel is supplied. In essence, while all fuel cells are electrochemical cells, not all electrochemical cells are fuel cells; the latter has a continuous reactant supply and often operates at higher efficiencies.
There are three different types of electrochemical cells?
false, there only two types of electrochemical cells. Wet and dry cells.
What is the difference between electrolyte and electrode?
An electrolyte is a substance that conducts electricity when dissolved in water or melted, typically consisting of ions. It facilitates the movement of charge within electrochemical cells. In contrast, an electrode is a conductor through which electric current enters or leaves an electrochemical cell, serving as the site for oxidation and reduction reactions. In summary, electrolytes enable charge transport, while electrodes are the interfaces for electrochemical reactions.
Where do chemical reactions occur in electrochemical cells?
Chemical reactions occur at the electrodes of electrochemical cells. At the anode, oxidation occurs as electrons are released into the circuit, and at the cathode, reduction occurs as electrons are accepted from the circuit. This flow of electrons creates an electric current in the cell.
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.
What is Function of electrochemical cells in oxidation?
in the cathode
What solid is commonly used as an inactive electrode in electrochemical cells?
Platinum is commonly used as an inactive electrode in electrochemical cells due to its inert nature and resistance to corrosion during the electrochemical reactions.
