Question

Explain how you could use displacement reactions to distinguish between
iron and zinc. You may use any solutions you choose.​

Answer 1

Answer:

Se it and make a choice

Explanation:

Displacement reactions involve a metal and a compound of a different metal. In a displacement reaction:

a more reactive metal will displace a less reactive metal from its compounds

Displacement reactions are easily seen when a salt of the less reactive metal is in the solution. During the reaction:

the more reactive metal gradually disappears as it forms a solution

the less reactive metal coats the surface of the more reactive metal

For example, magnesium is more reactive than copper. When a piece of magnesium is dipped into blue copper sulfate solution:

the blue colour fades as colourless magnesium sulfate solution forms

brown copper coats the surface of the magnesium

Magnesium powder is added to blue copper sulfate solution and when stirred, they change into a colourless magnesium sulfate solution and copper powder.
