Why does the colour of copper sulphate solution change when an iron nail is dipped in it? OR An iron nail is dipped in the solution of copper sulphate for about 30 minutes. State the change in colour observed. Give reason for the change. [CBSE 2015

Answer (1 of 2): Fe(s) + CuSO4(aq) - Cu(s) + FeSO4(aq) 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

Paheli prepared a blue coloured solution of copper sulphate in beaker A and placed an iron nail in it. Boojho prepared a yellowish green solution of ferrous sulphate in beaker B and placed a copper wire in it. What changes will they observe in the two beakers after an hour?

Assertion : When iron nail is dipped in copper sulphate solution, the iron nail becomes brownish in colour and the blue colour of copper solution fade. - 48736407

Why does the colour of copper sulphate solution change when an iron nail is dipped in it? Give an example of a double displacement reaction other than the one given in Activity 1.10. Identify the substances that are oxidised and the substances which are reduced in the following reactions

Answer (1 of 28): You would observe that the iron nails acquire a reddish-brown deposit whereas the copper sulphate solution turns to pale green from a bright blue. This is because of a displacement reaction taking place within the container. As iron is more reactive than copper and is placed ab

Aug 06, 2020 The Questions and Answers of Why does colour of copper sulphate solution change when an iron nail is dipped in it? are solved by group of students and teacher of NEET, which is also the largest student community of NEET

Answer: As the nail gets hotter, the Atoms get excited and emit Photons at a frequency depending on the temperature reached: From Infra red (not visible light but still photons are emitted) to visible light Frequencies Red—orange —- bright yellow and Whitish (mixsture of frequencies). This is a b

Dec 22, 2019 If an iron nail is dipped in the copper sulphate solution then iron displaces copper from the copper sulphate because iron is more reactive than copper. Therefore the colour of the copper sulphate solution changes. The reaction involved is as follows. Fe(s) +

Jun 17, 2021 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

Blue colour of the copper sulphate solution changes into green colour & then iron nail acquires a brownish look. This is because that iron is more reactive than copper. The following chemical reaction takes place in this activity. F e + C u S O 4 → F e S O 4 + C u In this reaction, iron displaces copper from C u S O 4 solution

Assertion :The colour of copper sulphate solution change when an iron nail is dipped in it. Reason: When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate. Q 5

Feb 13, 2020 Why does the Colour of copper sulphate change when an iron is dipped in it? 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

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. Note: We can also check the reactivity of a metal in reactivity series, where the metals have been arranged in a group (or series) according to their chemical reactivities

Feb 17, 2018 The colour of copper sulphate solution changes when an iron nail is dipped in it because iron is more reactive than copper. A substance which releases ions are called acids. 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

Iron nail, when dipped in a blue-coloured copper sulphate solution, reacts with it. The reaction causes a change in the colour of the solution from blue to green due to the formation of iron sulphate. A brownish deposit of copper is deposited on the iron nail. The reaction is repesented as:

Feb 23, 2013 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
