Why can Phosphoric acid be used to remove rust from a metal surface?
It reacts with Iron Oxide
What acid is used to remove rust?
Acid does not remove rust, however the use of phosphoric acid on rust converts the iron oxide to iron phosphate, which in turn can be painted without the fear of rust forming. The iron phosphate surface will not deteriorate the metal like iron oxide does.
Why does phosphoric acid remove rust?
Hydrochloride acid is hydrogen chloride or HCl. When HCl reacts with a metal, the metal replaces hydrogen in the compound, forming a metal chloride and hydrogen gas. Here's an example of zinc reacting to produce zinc chloride or ZnCl2. Zn + 2HCl --> ZnCl2 + H2
How does phosphoric acid affect metal oxides?
Phosphoric acid combines with iron oxide (rust) to form iron phosphide, which is inert - it doesn't corrode any further. The most common product made of phosphoric acid for this purpose is called Naval Jelly, available at any hardware store.
What is a biphosphate?
A biphosphate is any salt of phosphoric acid in which only one of the hydrogen atoms has been replaced by a metal ion.

Why do metals have to be sandpapered?
The reason why metal have to be clean with sandpaper is to remove the oxide layer on the surface of the metal. This is because most metal have a high tendency toward oxygen. The metal will react with oxygen in the air and form an oxide layer on the surface of the metal.

Why can you see your reflection better in a price of metal if you Polish the surface?
A clean metallic surface appears shiny because it is reflecting light. The interaction is due to the conductivity of the surface of the metal. When surface conditions change, the reflectivity is reduced.
It takes 208.4 kJ of energy to remove 1 mole of electrons from an atom on the surface of rubidium metal How much energy does it take to remove a single electron from an atom on the surface of solid r?

Do you have to remove your rings when you go through a metal detector?
Yes, or it will go off and they will make you remove them anyways, because most rings are made of metal.
Why does silver look shiny?
Because it is a metal and can be polished to a smooth shiny surface.
Why metal surface shine?
because it is very smooth therefore it reflects the light
What is sand machine?
Sand blasting machine is primarily used for cleaning the surface of any metal or non-metal which is damaged by rusting of metal, corrosion damage which is the major reason for the destruction of material. Under high-pressure conditions, sand blasting machines principally used to clean pain particles, remove rust particles, as well as it can remove unwanted particles and clean the surface of a particular metal or non-metal material. visit our website : sandblastingmachine.in

Does taping an electrical wire to a surface ground the current?
That would depend on the surface: wood surface - noplastic surface - noungrounded metal surface - nogrounded metal surface - yesetc.
