2. How do Metals react with Solutions of other Metal Salts?

3. Activity
Take a clean wire of copper and an iron nail.
Put the copper wire in a solution of iron sulphate and the iron nail in a solution of copper sulphate taken in test tubes .
Record your observations after 20 minutes.

4. In which test tube did you find that a reaction has occurred
*In which test tube did you find that a reaction has occurred? *On what basis can you say that a reaction has actually taken place? Write a balanced chemical equation for the reaction that has taken place. Name the type of reaction.

6. Reactive metals can displace less reactive metals from their compounds in solution or molten form.
We have seen in my previous video that all metals are not equally reactive. We checked the reactivity of various metals with oxygen, water and acids.
But all metals do not react with these reagents.

7. So we were not able to put all the metal samples we had collected in decreasing order of their reactivity.
Displacement reactions give better evidence about the reactivity of metals. It is simple and easy if metal A displaces metal B from its solution, it is more reactive than B.
Metal A + Salt solution of B → Salt solution of A + Metal B
