Why is platinum coated with platinum black used in the standard hydrogen electrode?
The platinum black provides a very high surface area that promotes the speed of reaction at the electrode and thereby virtually eliminates overpotential at the standard hydrogen electrode. An overpotential would lead to misleading values of potential of other electrodes compared with a standard hydrogen electrode that manifested overpotential.

Why is steel not suitable for making the positive electrode?
Actually alkaline batteries use a steel cup coated with carbon as the positive electrode. However the steel is purely structural to support the carbon coating and to prevent leakage of the electrolyte. It does not participate in generating the electricity.
What does an electrode contain?
An electrode typically contains a conductor, such as metal or carbon, that allows for the flow of electric current. It is usually coated or covered with materials that provide specific properties, such as conducting ions or catalyzing chemical reactions. Electrodes are commonly used in batteries, fuel cells, and various electrochemical processes.
What are metal cans coated with?
Depends on the metal used but it can be coated with tin, paint or paper.
What are electrodes made out of?
The positive electrode is a graphite rod (elemental carbon).
What are catalytic converters made of?
Catalytic converters are typically made of a ceramic or metallic catalyst support coated with a combination of metals such as platinum, palladium, and rhodium. These metals help to accelerate the chemical reactions that convert harmful emissions into less harmful substances like carbon dioxide, water vapor, and nitrogen.
Which welding process uses coated electrode?
The welding process that uses a coated electrode is Shielded Metal Arc Welding (SMAW), also known as stick welding. In this method, the electrode is coated with a flux that generates a shielding gas and a slag when heated, protecting the weld pool from atmospheric contamination. SMAW is widely used for its versatility and portability, making it suitable for various applications, including structural and repair work.
does 14kt cip stand for cased in platinum or if not what does it mean?
Cip is not a standard acronym, but generally it used as short-hand for clip on, such as a clip on earring.
Where can you find platinum coated nickel wire?
third world country black markets...
What does 7018 welding rod cost?
E7018 is a shielded metal arc welding (SMAW) electrode. 'E' stands for electrode. '70' stands for 70000 psi minimum as welded tensile strength. '1' designates the position the electrode can be welded in, in this case all positions. '8' classifies that the electrode is a low hydrogen electrode and contains a higher amount of iron powder.
Why electrodes are coated?
it insulates the electrode preventing formation of the arc except at the tipsit melts and acts as a protective flux over the joint, preventing oxidation

What is inside a Catalytic Converter of a 95 Chevy Lumina LS?
A Platinum and palladium coated ceramic matrix.
What arc welding process uses a consumable stick electrode?
The arc welding process that uses a consumable stick electrode is Shielded Metal Arc Welding (SMAW), commonly known as stick welding. In this process, an electric arc is formed between the coated stick electrode and the workpiece, melting both the electrode and the base metal to create a weld. The coating on the electrode provides a shielding gas and slag to protect the weld pool from contamination. SMAW is widely used for its versatility and effectiveness in various applications.
Ware is the catalis of an catalytic converter located?
The platinum is coated on the surfaces of the honeycomb or, on older models, on the ceramic beads.
What is smaw driving tools?
SMAW, or Shielded Metal Arc Welding, is a welding process that uses a consumable electrode coated in flux to create an electric arc between the electrode and the workpiece. The heat generated melts both the electrode and the base metal, allowing them to fuse together. Driving tools in SMAW refer to the equipment used to manipulate and control the welding process, including the welding machine, electrode holder, and protective gear. These tools ensure proper execution of the weld and safety for the welder.
