    Change in colour of copper sulphate occurs when an iron Nail is leaved in the copper sulphate solution for a time. The colour change happens from Blue to green. Equation for this Copper sulphate (blue)+ iron becomes iron sulphate (green)+ copper (brown deposit)

    2Thank You

    Harshitha U 3 years, 3 months ago

    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.

    The mode of nutrition in which organisms make the food by their own is called autotrophic. Auto=self, trophs=nourishment. The mode of nutrition in which organisms depend on others indirectly or directly for their food is called heterotrophic.hetro=others, trophs=nourishment. I hope this answer will help you

    Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions
