Question

A student is given an aqueous solution of chlorine and an aqueous solution of potassium bromide.
Explain how he can use these two solutions to compare the reactivity of chlorine with the reactivity of bromine.

Answer 1

Explanation:

When chlorine water is added to potassium bromide solution, chlorine will displace the bromine from the salt solution. The chlorine will be REDUCED (gain electrons) to chlorine ions. The bromide ions will be OXIDISED (lose electrons) to become bromine.

Answer 2

Answer :

The bromine in a potassium bromide solution is displaced by chlorine when chlorinated water is added. Chlorine will be converted to chlorine ions during the process (gain electrons). Bromine will be produced by oxidising bromide ions (losing electrons).

Explanation :

• Chlorine is a stronger oxidant than bromine.
• Chlorine is a stronger oxidant than bromine. Bromine from bromide salts is displaced as a result of the interaction with chlorine.
• A colourless potassium bromide solution becomes orange-red when chlorine water is added to it.
• This could be a highly explosive reaction.
• The only substance I notice forming here is potassium chloride, or KCI.
• Chlorine action liberates elemental bromine from bromide, resulting in a colour change.

Hence, 2KBr + Cl2 → 2KCl + Br2

• There is only one displacement reaction taking place. A single displacement reaction is what a redox reaction is.
• There is only one displacement reaction taking place. A single displacement reaction is what a redox reaction is. Bromine is quickly displaced from its salt because chlorine is a more reactive and strong oxidizer than bromine.

Further details:

• Potassium chloride is a drug that is used to prevent and treat potassium shortage.
• Potassium is also a necessary mineral for the proper functioning of your heart, muscles, kidneys, neurons, and digestive system.
• Various diseases, ailments, and drugs can deplete potassium levels in the body.
