Solution
When Sulphur Dioxide dissolve in water than sulphur trioxide is form and hydrogen gas released.
chemical equation :
SO2+H2O→SO3+H2
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 as 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.
