Iron lies above in the reactivity series and thus more reactive than copper. As a result,
the more reactive metal (iron) displaces a less reactive metal (copper) from its salt solution
(copper sulphate solution). Hence, the change in color.
Why does the colour of copper sulphate solution change when an iron nail is dipped in it Brainly?
The colour of copper sulphate solution changes when an iron nail is dipped in it
because iron is more reactive than copper
. … When an “iron nail” dips into the solution of “copper sulphate” than iron, the copper sulphate displaces copper because “iron” is “more reactive” than “copper”.
Why do the Colour and solution of copper sulphate change when we take a solution of copper sulphate in a breaker and put an iron nail in it?
When an iron nail immersed in the solution of copper sulphate than
iron displaces copper from the solution of copper sulphate because iron is more reactive than copper
. Therefore copper sulphate solution colour changes from blue to pale green.
Why does the colour of copper sulphate solution change when a zinc rod is placed in it?
Zinc is more reactive than copper
. Hence it easily displaces copper from it’s sulphate solution.So the blue color starts fading and copper gets deposited on the rod.
What happens when iron nails are put in copper sulphate solution?
Reaction of Iron Nails with Copper Sulphate Solution in Water. When an iron nail is dipped in copper sulphate solution,
a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green
. … This reaction is a single displacement reaction.
What is the colour of copper sulphate solution?
Answer: The solution of copper sulphate is
blue
.
What happened to the color of the copper sulfate solution?
When water is then added to the anhydrous compound, it turns back into the pentahydrate form, regaining its blue color
, and is known as blue vitriol. Copper(II) sulfate pentahydrate can easily be produced by crystallization from solution as copper(II) sulfate, which is hygroscopic.
What is the change in the colour following reaction Fe cuso4 feso4 CU?
So
Fe displaces Cu to form Iron Sulfate and Copper
. When an iron nail is dipped in copper sulphate, its colour changes because the sulphur in the copper sulphate reacts with the iron to form a new substance, iron sulphate which is green in colour.
Why is in given experiment color of the solution changes?
Answer: When universal indicator is added to a solution, the color change
can indicate the approximate pH of the solution
. Acids cause universal indicator solution to change from green toward red.
What would you observe when a strip of zinc is placed in copper sulphate solution?
Copper sulphate solution is blue in colour. When a zinc strip is dipped in it, the
solution’s colour slowly fades away
. This is because a displacement reaction occurs.
Which metal is displaced when zinc metal is put in the solution of copper sulphate?
On adding zinc to copper sulphate solution,
zinc
displaces copper from copper sulphate and forms zinc sulphate solution. It will undergo a redox reaction, called the displacement reaction of metal because zinc is more reactive than copper according to the reactivity series.
Can we store cuso4 in silver container give reasons?
As per the metals, in the reactivity series,
silver is less reactive than copper
, so there will be no displacement reaction between silver and copper. Hence copper sulphate solution can be stored in a silver container.
What happens when an iron nail is placed in copper sulphate solution Class 8?
When iron nails are placed in a copper sulfate solution,
iron displaces copper to form iron sulfate
. Slowly, the blue color of the copper sulfate solution turns into green.
Why does iron nail become brownish in colour and the Blue colour of copper sulphate solution fade?
When an iron nail is dipped in a solution of CuSO4, it displaces copper from the Solution, which gets deposited or precipitated as a red or red-brown residue. Also the blue colour of the solution gradually fades. … So
Fe displaces Cu to form Iron Sulphate
and Copper.
What becomes the colour of iron nails after they have been kept in the blue solution of copper sulphate for about 20 minutes?
Answer: on keeping iron nail on copper sulphate for twenty minutes a
green colour
is form because iron has higher electro positive character that copper.
What is the color of solution?
| Transition Metal Ion Color | Fe 3 + brown to yellow | CrO 4 2 – orange | Cr 2 O 7 2 – yellow | Ti 3 + purple |
|---|
