Ever heard Displacement Reaction , In Your Chemistry Class ?
For today’s Topic I will tell about Displacement Reactions .
Let’s take this Reaction for an instance
CuSO4 + Zn → ?
{ Copper sulphate } + { Zinc } → ?
Do You Know ? What will happen
It will become :
→ ZnSO4 + Cu
{ Zinc Sulphate } + { Copper }
Now take This For example :
FeSO4 + Cu → ?
{ Iron Sulphate } + { Copper } → ?
Result :
→ FeSO4 + Cu { No reaction Took Place }
Do You know Why did Reaction Took Place in Solution 1 But Didn’t In Solution 2 ?
This is because of Displacement Reaction .
Displacement Reaction States That :
If There is a Compound , And a more reactive element is in the equation than the other element , then it will replace it . Like if we look in the reactivity table .
| Caesium |
|---|
| Francium |
| Rubidium |
| Potassium |
| Sodium |
| Lithium |
| Barium |
| Radium |
| Strontium |
| Calcium |
| Magnesium |
| Beryllium |
| Aluminium |
| Titanium |
| Manganese |
| Zinc |
| Chromium |
| Iron |
| Cadmium |
| Cobalt |
| Nickel |
| Tin |
| Lead |
| Hydrogen |
| Antimony |
| Bismuth |
| Copper |
| Tungsten |
| Mercury |
| Silver |
| Platinum |
| Gold |
Iron is more reactive than copper , So It wasn’t replaced But ! If we take copper sulfate it is less reactive than zinc , so it was replaced resulting zinc sulfate and copper in the reaction . For any two metals in the series, the metal placed higher in the series can displace lower metals or less reactive metals .
That’s For Today
Byeee !
