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

False. Pb is lower than Al in the reactivity series. It cannot replace aluminium in AlCl3

Answer 2

Answer: The correct answer is False.

Step-by-step explanation:

Single displacement reactions are defined as the reactions in which more reactive element replaces a less reactive element from its chemical reaction.

`A+BC\rightarrow AC+B`

A is more reactive element than reactive B.

The reactivity of metals is judged by the series known as reactivity series. Elements lying above in the series are more reactive than the elements lying below in the series.

For the reaction between lead and aluminium chloride, the reaction does not take place because lead lies below in the reactivity series than aluminium. Hence, lead cannot displace aluminium from its chemical reaction.

`Pb+AlCl_3\rightarrow \text{No reaction}`

Hence, the correct answer is False.
