Question

10 examples of displacement reaction in daily life

Answer 1

Answer:

when a less reactive metal displaces with a more reactive metal it is known as displacement reaction.

Answer 2

Answer:

1) magnesium+copper oxide = magnesium oxide+copper

they switch places because magnesium is more reactive metal.

2) iron    +    copper(II) sulfate =   iron sulfate  + copper.

Fe(s)      +      CuSO4(aq)            FeSO4(aq)   +   Cu(s)

Copper(II) sulfate is blue, iron sulfate is colourless.

During the reaction the blue solution loses its colour

and the iron metal is seen to turn pink-brown

as the displaced copper becomes deposited on it.

3) tin   +   lead chloride         tin chloride  +  lead.

Sn(s)   +   PbCl2(aq)             SnCl2(aq)   +   Pb(s)

4) copper  +  silver nitrate          copper nitrate  +  silver.

Cu(s)   +   2AgNO3(aq)          Cu(NO3)2(aq)   +   2Ag(s)

5) chlorine + sodium bromide → sodium chloride + bromine
