Question

explain chemical. displacement reaction with an activity ​

Answer 1

Answer:

Definition:- In a displacement reaction, one element displaces another from its compound and take its place therein.

Explanation:

Activity: See the pic above

Answer 2

Answer:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.

Explanation:

Spotting tile, with at least 16 depressions (or two smaller tiles)

Dropping (teat) pipette

Beaker (100 cm3)

Felt tip pen or other means of labelling

Chemicals

Access to about 5 cm3 each of the following 0.1 M metal salt solutions (note 1):

Copper(II) sulfate (or nitrate(V))

Lead(II) nitrate (TOXIC, DANGEROUS FOR THE ENVIRONMENT)

Magnesium sulfate (or nitrate(V))

Zinc sulfate (or nitrate(V))

Five samples, approximately 1 cm lengths or squares, of each the following metals (note 2):

Copper foil

Lead foil (TOXIC, DANGEROUS FOR THE ENVIRONMENT)

Magnesium ribbon

Zinc foil

Procedure

Using a dropping pipette, put a little of the zinc sulfate (or nitrate) solution in four of the depressions in the spotting tile, using the illustration below as a guide. Label this row with the name of the solution. Rinse the pipette well with water afterwards.

Do this for each metal ion solution in turn, rinsing the pipette when you change solution.

Put a piece of each metal in each of the solutions, using the illustration as a guide.

Over the next few minutes observe which mixtures have reacted and which have not.
