Question

When Pb and AlCl3 react together, lead (Pb) can replace aluminum (Al) in the compound because lead is lower on the activity series. T/F

Answer 1

i just took the test and the correct answer is FALSE

Answer 2

Answer: False

Explanation: In a single replacement reaction, one metal can only be replaced by another metal if the metal which is replaced is less reactive than the metal coming to take its place. For example, Cu is less reactive than Zn. So, Cu could easily be replaced by Zn.

`Zn(s)+CuSO_4(aq)\rightarrow ZnSO_4(aq)+Cu(s)`

Pb is less reactive than Al and so it can not replace Al from
`AlCl_3` .

Hence, the given statement is false.
