Iron powder is added in Copper salt what is the identity of the test result
The identity of the test result would be a single replacement reaction, also known as a displacement reaction. This is because the Iron atoms in the iron powder will replace the Copper atoms in the copper salt, forming Iron Salt and Copper powder. This will result in a color change from the original blue-green color of the Copper salt to a reddish-brown color of the Iron salt. The test result confirms that Iron is more reactive than Copper.
When iron powder is added to a copper salt, a chemical reaction known as a displacement reaction occurs. In this reaction, iron displaces copper from the salt, resulting in a new compound and a change in color.
The identity of the test result can be determined by observing the color change. Initially, the copper salt may have a blue or green color, depending on the specific salt used. When the iron powder is added, the color of the solution may change to brown or orange.
Therefore, the identity of the test result can be determined as a color change from blue or green (copper salt) to brown or orange.
