What is the electrode?
An electrode is an electrical conductor that makes contact with the nonmetallic circuit parts of a circuit, such as an electrolyte, semiconductor or vacuum. If in an electrochemical cell, this is also known as an anode or cathode.
What is electrode and its types?
Electrodes are conductors by which electrons flow through to generate a current. There are two types of electrodes, cathodes, and anodes. Cathode attracts the positively charged cations. Anode attracts negatively charged anions. Electrodes are commonly made of metals such as platinum and zinc.
How do electrodes work?
The Function of a Working Electrode: The current produced from the electrochemical reaction at the working electrode is balanced by a current flowing in the opposite direction at the counter electrode. The reference electrode acts as a reference point for the redox couple.
What is electrode in science class 8?
An electrode is a conductor of electricity that can carry electric current into non-metals and other poor conductors of electricity. The positively charged electrode is called anode and the negatively charged electrode is called cathode.
What is electrode example?
Types and Examples of Electrodes Some commonly used inert electrodes include platinum, gold, graphite(carbon), and rhodium. Some reactive electrodes include zinc, copper, lead, and silver.
What is electrode Class 9?
An Electrode can be defined as the point where current either enters or leaves the electrolyte or circuit. When the current leaves the Electrode it is known as the cathode while when the current enters the Electrode it is known as an anode. Electrodes are the main component of electrochemical cells.
What are the four types of electrode?
This article throws light upon the four types of electrode used in electrochemical techniques. The four types of electrode are: (1) The pH Electrode (2) Ion Selective and Gas Sensing Electrodes (3) The Clark Oxygen Electrode and (4) The Leaf Disc Electrode.
What is electrode give an example?
Some commonly used inert electrodes: graphite(carbon), platinum, gold, and rhodium. Some commonly used reactive (or involved) electrodes: copper, zinc, lead, and silver.
What is electrode surface?
A small device that is attached to the skin to measure or cause electrical activity in the tissue under it. Surface electrodes may be used to look for problems with muscles and nerves.
What are electrodes Class 9?
What is electrode reaction?
Electrode reactions can be classified into two groups: one in which an electron transfer takes place across the electrode interface, such as ferric–ferrous redox reaction ( Fe aq 3+ + e = Fe aq 2+ ) ; and the other in which an ion transfer takes place across the electrode interface, such as iron dissolution–deposition …
