Book Free DemoSamples 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:
Metals | Iron (II) sulphate | Copper (II) sulphate |
\(A\) | No reaction | Displacement |
\(B\) | Displacement | |
\(C\) | No reaction | No reaction |
\(D\) | No reaction | No reaction |
Metals | Zinc sulphate | Silver nitrate |
\(A\) | ||
\(B\) | No reaction | |
\(C\) | No reaction | Displacement |
\(D\) | No reaction | No reaction |
Use the table above to answer the following questions about metals \(A\), \(B\), \(C\) and \(D\).
i). Which is the most reactive metal?
is the most reactive metal.
ii). What would you observe if \(B\) is added to a solution of copper(II) sulphate?
When metal \(B\) is added to copper (II) sulphate solution, a displacement reaction occurs, causing the blue colour sulphate solution a copper deposit to form on metal \(B\).
iii). Arrange the metals \(A\), \(B\), \(C\) and \(D\) in the order of decreasing reactivity.
Tthe decreasing order of reactivity of the metals is .
