The Reactivity Series (GCSE Chemistry)

A student adds a piece of magnesium ribbon to dilute hydrochloric acid and collects the gas evolved. Which test result would confirm the gas is hydrogen?

A metal higher in the reactivity series will displace a metal lower in the series from its salt solution. Which statement best describes a displacement reaction?

A student places a strip of copper into a solution of silver nitrate. Which observation confirms a displacement reaction has occurred?

Which factor is the main reason molten ionic compounds conduct electricity while the solid ionic compounds do not?

When a reactive metal is added to a salt solution of a less reactive metal, which species is oxidised?

Why do more reactive metals tend to corrode more quickly in air and water?

Which of these methods produces a pure metal from its molten ionic compound using electricity?

Which method is commonly used to extract a metal that is more reactive than carbon (for example, aluminium)?

Which pair of metals would you expect to produce a displacement reaction when a strip of the first metal is placed in a solution of the second metal’s salt?

What is the correct ionic equation for the reaction when zinc metal displaces copper from copper(II) sulfate?

Which of the following correctly explains why aluminium is often extracted using electrolysis rather than reduction with carbon?
