Question

When Iron nails are added to an aquous solution of copper sulphate, a chemical change occurs, which of the following is NOT true about this reaction?

a)
Blue colour of the solution fades.
b)
Iron nails become brownish in colour.
c)
It is a displacement reaction.
d)
Blue colour of the solution does not fades.

Correct answer is option 'D'. Can you explain this answer?

Answer

Iron nails dissolves completely because iron is more reactive than copper.After this Iron displace copper and form iron sulphate .

Answer

Fe(s)+CuSO4⟶Cu(s)+FeSO4

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 shows that iron is more reactive than copper as it displaces copper from its solution and iron passes into solution as Fe

2+ ions and ferrous sulphate solution is formed.

Answer

Iron is a hard substance which cannot be dissolved in solution

I hope it is helpful to you......

Answer

We all know that iron is more reactive then copper so iron displaces copper from its salt sol ution that's y the statement d is wrong

Answer

Explanation:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. In this case, iron is more reactive than copper, so it displaces copper from copper sulphate. Hence, option C is true.

When iron nails are added to an aqueous solution of copper sulphate, the following observations are made:

1. Blue colour of the solution fades: This is because when iron nails are added to copper sulphate solution, copper from copper sulphate is displaced by iron and forms iron sulphate. Hence, the blue colour of the solution fades. This is true, so option A is true.

2. Iron nails become brownish in colour: This is because iron reacts with copper sulphate to form iron sulphate and copper. The copper gets deposited on the surface of iron nails, which gives them a brownish appearance. Hence, option B is true.

3. Iron nails dissolve completely: This statement is false because iron does not dissolve completely in copper sulphate solution. Iron reacts with copper sulphate to form iron sulphate and copper, but the iron nails do not dissolve. Hence, option D is false.

Therefore, the correct answer is option D, i.e. iron nails do not dissolve completely in the solution.

Answer

Option D is correct...

Answer

When iron nail is dipped in Copper sulphate, it takes reaction between them and Copper sulphate changes its color from blue to light green.

This should determine more reactive than copper.

This could replace copper from CuSO4, and blue color and FeSO4 is in light green color. It will change its colors due to copper iron nails functions.

Answer

In this reaction iron is more reactive than copper hence iron react with cuper solution and displaced cu
CuSO4 +Fe. -Cu+FeSO4
that's why totally iron react and convert into FeSO4 and Cu is found in crystals in beaker

Answer

As fe is more reactive than cu so, it displaces cu from it's aq. solution .
The blue colour of copper sulphate fades away and pale green color appears.
This reaction is an example of displacement reaction.

Answer

As we know that when iron nails is dipped in copper sulphate solution than iron displaces copper from copper sulphate solution bcz iron is more reactive than copper and the colour of copper sulphate chng     so the statement given by here iron nails dissolves completely is  not true

Answer

Fe(s) + CuSO4 ⟶ Cu(s) + FeSO4

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 shows that iron is more reactive than copper as it displaces copper from its solution and iron passes into solution as Fe2+ions and ferrous sulphate solution is formed
