Question

Why do the colour & solution of copper sulphate change when we take a solution of copper sulphate in a beaker and put an iron nail in it? Connects process and event with cause.

Answer 1

Answer:

the copper in the copper sulphate solution gets deposited on the iron nail thus changing the colour of the solution and iron nail

Explanation:

the cause is due to Copper being easily displaced as compared to other solutions

Answer 2

Answer:

Explanation:

ANSWER:-

When the iron nail is dipped:-

• Then , the blue colour of copper sulphate changes to green colour.
• This is because iron is more reactive than copper.
• So the iron displaces out copper.
• Also we can see that earlier Iron nail was silver in color.
• The following shows the reaction taken as:-

$CuSO_4+Fe \longrightarrow FeSO_4+Cu$

• CuSO4 is copper Sulphate
• Fe is Iron commonly called Ferrous
• FeSO4 is Iron sulphate
• And also , Cu is copper.

1. The change in colour takes place from blue to green.
2. The Iron nail colour changes from silver to red.
