Trends in Reactivity
This practical lesson covers:
- How to identify the reaction trend of Group 7 elements using displacement reactions
Investigating the trend in reactivity of group 7 elements
Aim
The aim of this practical is to identify the reactivity trend of group 7 elements using displacement reactions.
Background information
Displacement reactions can be used to identify the pattern of reactivity of a group of elements. Adding universal indicator allows us to identify if a displacement reaction has taken place by observing a colour change. In this practical, you will be observing colour changes that take place during displacement reactions to identify the trend in reactivity of the group 7 elements.
What is the aim of this practical?
To identify the reactivity trend of group 7 elements using redox reactions
To identify the reactivity trend of group 1 elements using displacement reactions
To identify the reactivity trend of group 7 elements using displacement reactions

What is a displacement reaction?
A chemical reaction where a more reactive element displaces a less reactive element from its compound
A chemical reaction where a less reactive element displaces a more reactive element from its compound
A chemical reaction where two elements exchange places in their compounds

What is the purpose of adding universal indicator in this practical?
To identify the concentration of the solution
To identify if a displacement reaction has taken place by observing a colour change
To identify the pH of the solution
