It is a blue crystalline solid
When copper is mixed with copper nitrate, a chemical reaction occurs where the copper in the copper nitrate displaces the copper in the solid copper, forming copper(II) nitrate and releasing nitrogen dioxide gas. This reaction is a redox reaction, where copper is oxidized and the copper ions in the solution are reduced.
copper (thiocyanate)2 and potassium nitrate
When silver nitrate is added to copper, a redox reaction occurs where the Cu from copper displaces the Ag from silver nitrate. This results in the formation of copper nitrate and silver metal as a solid precipitate.
Copper nitrate is a blue crystalline solid and is soluble in water. It has a melting point of 114 °C.
Copper nitrate is a chemical compound and not a state like a U.S. state. It is a solid compound at room temperature.
Silver nitrate does not precipitate in this case; elemental silver does. In this reaction, silver nitrate reacts with copper to form elemental silver and copper II nitrate. The silver, which is a metal, is insoluble in water.
copper is placed above the silver in the ractivity series which indicates that copper is more reactive than silver . when a copper coin is kept immersed in a solution of siler nitrate ,silver from its solution will deposit on copper coin . copper slowly displaces silver from the silver nitrate solution and the colour of solution changes from colourless to blue due to the formation of copper nitrate . the copper coin will disappear and silver will percipate out .
Either sodium carbonate or copper carbonate
By dissolving the silver nitrate in water, then stirring finely divided copper into the water. The copper will displace silver from the silver nitrate as a solid and form copper nitrate in the solution.
When copper is added to silver nitrate, a single displacement reaction occurs. The copper will displace the silver in the compound, forming copper(II) nitrate and silver. The silver will precipitate out of solution as a solid.
Copper nitrate is typically a blue-green color in its solid form. When dissolved in water, it forms a blue solution.
When hydrogen gas is passed through a solution of copper nitrate, a redox reaction occurs where the copper ion gains electrons to form solid copper metal. Nitrate ions are reduced to nitrogen oxides or nitrogen gas depending on the reaction conditions.
