Question

Metals bond with halogens to form colorless metal halides. During an experiment, chlorine water was added to a solution of potassium bromide. A record of the experiment is shown.

Which of the following conclusions can be made about this chemical reaction based on the data? (1 point)
O Chlorine is more reactive than bromine.
Potassium bromide and chlorine do not react.
O Potassium metal is formed from a single replacement reaction.
O Bromine solution is colorless and is formed due to a single replacement reaction.

Answer 1

O Chlorine is more reactive than bromine.

Step-by-step explanation:

From this experiment we can conclude that chlorine is more reactive than bromine and it is the reason why the reaction is able to proceed.

• The reaction is a single displacement reaction in which the position of an element in the activity series is very important.
• Since chlorine is more electronegative and highly reactive when compared to bromine, it will displace bromine from the solution of potassium bromide.
• So, we have product of potassium chloride and the bromide.
