Sub Topic Name : Displacement Reaction |
|
Introduction
Diagram showing 2 pairs getting mutually displaced (I feel not appropriate, it gives example of double displacement in the intro picture but we are discussing about single displacement)
Pre-Requisites:
Basic knowledge about reactivity of metals
Activity:
Observe that a iron nail gets copper colour when immersed in CuSO4 Solution
Real Life Question:
Why does any copper coin looks brand new, if it is immersed in vinegar with iron nail?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Reactivity of metal | The ability of a metal to lose electrons and take part in a chemical reaction |
| Redox reaction | Both reduction and oxidation occurring in a reaction. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Reactivity Chart | To locate an element in the reactivity chart and to understand which metal can replace the other. |
Real life uses :
Electroplating, metal coating.
Practical examples around us
| Examples | Explainations |
|---|---|
| Coating of copper on iron nail in CuSO4 solution | Since Iron is above Copper in the reactivity series, Iron is more reactive than Copper. Hence Iron replaces Copper from CuSO4 solution and forms FeSO4 and a copper coating on the iron nail |
What you learn in Theory:
Single Displacement Reaction
What you learn in Practice:
Reactivity of metals, order of reactivity, redox reaction and reason behind displacement reaction.
