Phosphorus Reacts with Bromine - Periodic Table of Videos

TL;DR

The Periodic Videos team celebrates their 15th birthday by conducting a series of reactions using phosphorus and bromine.

Transcript

I pointed out to Brady that very soon is going to be our 15th birthday from our first periodic video and we wanted to celebrate it and being Brady he wanted to do something whizzy to excite you and he suggested that 15th birthday should be element number 15 which is phosphorus and we have done a number of videos on phosphorus our standard video on ...

Key Insights

• 🥳 The Periodic Videos team marks their 15th birthday with a unique phosphorus and bromine experiment.
• 👨‍🦳 Red phosphorus ignites when introduced to bromine, while white phosphorus reacts more slowly.
• ❓ The surface area of the phosphorus affects its reactivity, with finer particles reacting more intensely.

Questions & Answers

Q: How is the Periodic Videos team celebrating their 15th birthday?

The team is celebrating by conducting a new experiment involving the reaction between phosphorus and bromine.

Q: What are the different forms of phosphorus used in the experiment?

The team uses both red phosphorus and white phosphorus in the experiment.

Q: What happens when red phosphorus is introduced to bromine?

When red phosphorus is introduced to bromine, it ignites and burns.

Q: Why did the reaction with matches containing phosphorus not occur?

The reaction with matches containing phosphorus did not occur, possibly due to the matches being old.

Q: How does white phosphorus react compared to red phosphorus?

White phosphorus reacts more slowly compared to red phosphorus, but the reaction improves when the white phosphorus is dried.

Q: What is the role of surface area in these reactions?

The team notes that the surface area of the phosphorus affects its reactivity, with the finer powder of red phosphorus reacting more intensely.

Q: What happens when bromine is poured over white phosphorus?

When bromine is poured over white phosphorus, it burns in a ceramic dish, but the reaction is not extremely dramatic.

Q: What happens when liquid bromine is applied to red phosphorus?

When liquid bromine is applied to red phosphorus, it reacts well and produces impressive flames.

Summary & Key Takeaways

• The team decides to celebrate their 15th birthday by conducting a novel experiment involving the reaction between phosphorus and bromine.

• They begin with red phosphorus and observe it igniting when introduced to bromine.

• They also attempt to ignite matches containing phosphorus in bromine, but the reaction does not occur. They then try white phosphorus and, after drying it, observe a slow reaction compared to red phosphorus.
