between nickel and zinc in transtional element
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 .
So that it would still look its age.
as silver is less reactive than copper the silver when immersed will loose its electrons and the copper will displace it. i apologize if it is the wrong answer.... this is actually a guess :P
When a silver spoon is kept in an aqueous solution of copper sulfate, a redox reaction takes place where silver displaces copper from the solution. As a result, silver ions in the solution get reduced and deposit copper onto the spoon. This process is known as displacement reaction, where a more reactive metal displaces a less reactive metal in a compound.
His father was a leaseholder of copper mines and smelters and his mother kept house.
The Iron rod(Fe) reacts with the Copper Sulphate. Substitution reaction takes place. Fe+CuSO4--> FeSO4 + Cu
When copper sulfate is mixed with water in a beaker and left on its own, it forms a homogeneous mixture called a solution.
The term used to describe the mixing of copper sulphate and water in a beaker is "dissolution." This process involves the copper sulphate particles dispersing and mixing with the water to form a homogeneous solution.
fehling a is copper sulphate and fehling b is alkaline solution of sodium pottasium tartarate
The iron rod turned brown because it underwent a chemical reaction with the copper ions in the copper sulfate solution, forming copper metal on the surface of the iron. Another change you might observe is that the copper sulfate solution may become lighter in color as some of the copper ions plate onto the iron rod.
Copper is typically stored in a dry and cool location to prevent oxidation and corrosion. It is often kept in airtight containers or packaging to minimize exposure to air and moisture. Additionally, copper should be stored away from sources of heat and sunlight to maintain its quality.
When a silver spoon is immersed in aqueous copper sulphate solution, a displacement reaction occurs. The silver spoon will react with the copper sulphate, displacing the copper ions and forming silver sulphate solution. Over time, the silver spoon will start to turn slightly reddish as a thin layer of copper is deposited on its surface.
