The observations made are tabulated below: Metal Iron (II) sulphate Copper (II) sulphate Zinc sulphate Silver nitrate A No reaction Displacement - - B Displacement - No reaction - C No reaction No reaction No reaction Displacement D No reaction No reaction No reaction No reaction Answer the following questions based on above information:(i) Which is the most active metal and why?(ii) What would be observed if B is added to a solution of copper (II) sulphate and why?(iii) Arrange the metals A, B, C and D in order of increasing reactivity.(iv) Container of which metal can be used to store both zinc sulphate solution and silver nitrate solution. Give reason for your choice.(v) Which of the above solutions can be easily stored in a computer made up of any of these metals?
