1. The solution of ZnSO4 ,FeSO4 and CuSO4 are taken in three different test tubes .Suppose , an iron nail is kept immersed in each one. b) What is the reaction taking place here?
Answers
Answer:
yes it's correct question but I don't have answer sorry
Electrochemical series is a series in which atoms of metals are arranged in an orderly manner according to the ease with which it can lose electrons to form positively charged metal ions.
The metals which have a higher position in the series can displace the metals placed lower than it.
According to the electrochemical series, zinc is placed above iron which is placed above copper. So, the iron present in the iron nail can displace only copper from its solution. So, hydrated copper sulphate which is blue in colour changes to pale green colour during this displacement reaction.
Final Answer
The test tube in which iron nail is immersed in the copper sulphate solution will undergo a colour change.
