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.MetalIron(II) SulphateCopper(II) sulphateZinc sulphateSilver nitrateANo reactionDisplacementBDisplacementNo reactionCNo reactionNo reactionNo reactionDisplacementDNo reactionNo reactionNo reactionNo reaction Use the Table above to answer the following questions about metals A, B, C and D.1. Which is the most reactive metal?2. What would you observe if B is added to a solution of Copper(II) sulphate?3. Arrange the metals A, B, C and D in the order of decreasing reactivity. |

Answer» 1. B is most reactive metal. 2. If B is added to a solution of copper sulphate it displaces copper from copper sulphate. 3. If metals are written in the order of decreasing reactivity it is B > A > C > D. |
