Iron powder is added in Copper salt what is the identity of the test result

Answer 1

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.
