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- 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 Use the Table above to answer the following question about metals: A , B , C , and D . Which is the most reactive metal?

From the given table we can write the following observations: 1) A is less reactive than F e but more reactive than C u . 2) B is more reactive than F e but less reactive than Z n . 3) C is more reactive than A g but less reactive than F e , C u a n d Z n . 4) D is less reactive than F e , C u , Z n , A g . Hence, B is more reactive as per the drawn conclusions from statements 1, 2, 3, 4.

What would you observe if B is added to a solution of Copper I I sulphate?

The blue colour of copper sulphate solution disappears, and a reddish-brown copper metal is deposited on the metal B . This is because B is more reactive than Cu and it displaces copper from its solution.

Arrange the metals A , B , C , and D in the order of decreasing reactivity

From the given table we can write the following observations: 1) A is less reactive than F e but more reactive than C u . 2) B is more reactive than F e but less reactive than Z n . 3) C is more reactive than A g but less reactive than F e , C u a n d Z n . 4) D is less reactive than F e , C u , Z n , A g . B > A > C > D is the order of reactivity.

Give reasons- Platinum, gold and silver are used to make jewellery.

Platinum, gold and silver are used to make jewellery because they are highly malleable and ductile as well as lustrous. Also, they are less reactive and do not corrode easily.

Explain the meaning of malleable and ductile
