The reactivity series

What is the reactivity series?

The reactivity series is a list of metals arranged in order of their reactivity, from highest to lowest.

Which metal is the most reactive in the reactivity series?

Potassium is the most reactive metal in the reactivity series.

Which metal is the least reactive in the reactivity series?

Platinum is one of the least reactive metals in the series.

How does the reactivity series help us predict reactions?

The reactivity series can predict which metals will react with others based on their relative reactivity.

What type of reaction occurs when a metal reacts with an acid?

A displacement reaction, producing salt and hydrogen gas.

What metal is used to extract iron from its ore in the blast furnace?

Carbon is used to extract iron from iron oxide (Fe₂O₃) in the blast furnace.

How does zinc react with copper sulfate?

Zinc displaces copper from copper sulfate, forming zinc sulfate and copper metal.

Why is gold considered unreactive?

Gold is unreactive because it does not easily form compounds with other elements.

Which metals react vigorously with water?

Sodium, potassium, and lithium react vigorously with water to form hydroxides and hydrogen gas.

How is the reactivity series related to displacement reactions?

A more reactive metal can displace a less reactive metal from its compound in a displacement reaction.
