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.
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.
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.
How do you use powder in a sentence?
The product is then powder coated to a choice of RAL colors in the standard range.

What has the author Sally-Ann Sheppard written?
Sally-Ann Sheppard has written: 'Characterisation of dispersed, platinum-coated fuel cell electrodes'
Where to buy enteric coated turmeric capsules?
Go to Physician Naturals. They offer enteric coated Curcumin, along with Bioperine (black pepper) and Bromelain to help absorption. Seems to be the gold standard.
What is platinum overlay?
Platinum overlay is similar to Rhodium plating, it is just an extremely thin layer of platinum meant to enhance the silver or base metal content. The reason we are seeing an up rise of platinum overlay is due to the diminishing cost of platinum, and because it is more widely known to the public than rhodium. Side Note: I find the whole " platinum overlay" marketing trend to be hyperbole, considering Rhodium is cheaper and most all genuine platinum jewelry is coated with rhodium to bring out luster.
