Question
When iron nails are added to an aqueous solution of copper sulphate, a chemical change occurs. Which of the following is not true about this reaction?
Answer: Option D
:
D
When iron nails are added to an aqueous solution of copper sulphate, a displacement reaction occurs in which iron displaces copper from its solution which leads to fading of the blue colour of solution. After some time, the displaced copper settles down on the iron nails and reduces the surface available for reaction. So, the iron nailsdonot dissolve completely. The reaction involved is:
Fe(s)+CuSO4(aq)→FeSO4(aq)+Cu (s)
