Question

 Which element of the following would be the worst to use for pipes and fillings in the rainwater harvesting system? Explain by referring to the reactivity of each and to the nature of the ions that form. Support your answer using electronic configuration and periodic trends.

Aluminum, Copper, Lead

Answer 1

Answer:

copper

because it is uses

Answer 2

Rainwater harvesting:

Explanation:

• Rainwater harvesting is the collection and storage of rain, rather than flowing it to runoff.
• Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit, aquifer, or reservoir with percolation so that it seeps down and restores the groundwater.

• Aluminium does not react very well within the oxygen in the air but it is in fact quite a reactive metal.
• The reason it does not react is that it has already reacted.
• The aluminium oxide has formed in a thin, tightly bonded layer that protects the aluminium foil from further attack.

• If we look at this activity series, copper will indeed react, but it's not too great at it.
• You can see that the elements at the bottom are best suitable as wire and that's not a coincidence.
• These elements do not oxidize (donate electrons) easily which explains why they are less reactive.

• Lead is a reactive metal however, its reactivity is somewhat inhibited by the formation of an outer skin of protective compounds.
• For example, when a freshly cut piece of lead metal is exposed to the air, it quickly reacts with oxygen to create a thin outer layer of lead oxide.

• According to observations, lead is the worst metal used for making pipes and fillings in the rainwater harvesting system.
