1.	Samples of four metals A , B ,C and D were taken and added to the following solution one by one. The results obtained have been tabulated as follows: Use the table above to answer the following question about metals A,B ,C and D. (i) Which is the most reactive metal? (ii) What would you observe, if B is added to a solution of copper(II) sulphate? (iii) Arrange the metals A,B,C and D in the order of decreasing reactivity.
Answer» SOLUTION :(i) B is most reactive (ii) B will DISPLACE copper from copper (II) SULPHATE (iii) `B gt A gt C gt D`
