because a thin-protective layer of slag is formed over the molten metal
Copper reacts with nitric acid because it is a stronger oxidizing agent compared to hydrochloric acid. Nitric acid can easily oxidize copper to form copper(II) ions, while HCl lacks this oxidizing capability and therefore does not react with copper.
Electrical wiring: Copper alloys such as brass and bronze are commonly used in electrical wiring systems due to their high conductivity and corrosion resistance. Marine applications: Copper-nickel alloys are used in marine environments for applications like propeller shafts and seawater piping due to their resistance to corrosion in saltwater. Decorative applications: Copper alloys like bronze are used in architectural elements and art due to their attractive appearance and ability to be easily shaped and detailed.
Examples of heterogeneous alloys include brass (copper and zinc), bronze (copper and tin), and steel (iron and carbon). These alloys contain two or more distinct metallic elements that are not soluble in each other, resulting in a heterogeneous structure.
Brass and bronze are both alloys made primarily of copper. Brass is made primarily of copper and zinc, while bronze is made primarily of copper and tin. Both alloys have a warm, golden hue and are commonly used in applications such as musical instruments and decorative items.
Some common metals that mix with copper to form alloys include zinc to create brass, tin to create bronze, and nickel to create cupronickel. These alloys are used in various applications due to their improved properties compared to pure copper.
Copper grades are divided into six families: coppers, dilute copper alloys, brasses, bronzes, copper-nickel alloys, and nickel-silver alloys. The grade depends on the composition.

The oxidizing agent in the conversion of copper metal to copper II ion is the other half of the redox reaction. In this case, it would be the substance that gains electrons, which is the oxidizing agent. In this reaction, the oxidizing agent would be whatever substance oxidizes the copper metal (loses electrons) to form copper II ion. This is typically noted as the substance that has "reduced" the other reactant.
Copper reacts with nitric acid because it is a stronger oxidizing agent compared to hydrochloric acid. Nitric acid can easily oxidize copper to form copper(II) ions, while HCl lacks this oxidizing capability and therefore does not react with copper.

Copper (as a metal or alloys) is safe.
copper and alloys of copper
Iridium can form alloys with copper.
NONE copper is an element and contains only copper - alloys (mixtures of copper combined with other metals) such as brass (copper and zinc) and bronze (copper and tin) both look different and cause the alloys of copper to have different characteristics
Copper alloys are more useful than pure copper because they have enhanced properties such as increased strength, hardness, and corrosion resistance. By combining copper with other metals, alloys can be tailored to suit specific applications, making them more versatile and suitable for a wider range of uses than pure copper.
