The Flame Test Experiment- The Chemistry of Colorful Flames

[@DTMEarth]

This is really useful! I am Grade 12 A/L student from Sri Lanka. My AL exam is coming up soon. I couldn't go to school on the day of this practical test. Now It is no problem. I saw every colors PERFECT.. And u taught very very well...Finaly, thank u sooo much madam for ur help. Good Luck!

[@ChemCampwithMrsNewman]

So glad it was helpful! Thank you for watching and your kind words. I wish the best of luck in your studies!

[@ozgamerab8780]

I hope you did excellent in your exam!

I'm Sri Lankan too

[@赵诗杰-s8b]

Thanks, I am a chem teacher in Guizhou, China. We don't have experimental equipment, and your video will save my class.

[@ChemCampwithMrsNewman]

Very glad to hear this will help you and your class! I've taught in classrooms with very limited experimental equipment and it makes teaching and learning chemistry so much more challenging.

Hey Is not KZbin ban in China ..???

[@edwardcunningham6315]

This video gets 👍👍. I'm a retired veteran and I've always enjoyed chemistry since I was a teen. I've had a bit of time now to chase after some of my hobbies and your videos helped clear up a little bit more on the piriodic table and safe methods of testing metals as well as consideration of purity. I did a version of the color differences but used a circular burner in a camping stove. The flame "spectrograph" turned out intense 😁👍. Concentrate the same metals in different amounts was a highlight 😀. PS, All due safety was applied during the experiments👍❤️

[@ChemCampwithMrsNewman]

Thank you very much for your service! So glad you enjoyed the video and safely enjoyed doing the chemistry 🧪

[@sophiaflores3717]

this was super useful! I'm doing my flame test lab for chemistry tomorrow tysm!

[@ChemCampwithMrsNewman]

I hope you enjoyed your lab! It’s one of Chemistry’s finest. Makes my heart happy you found this video useful 💜

thankyouu soo much for the beautiful demonstration miss!

Very Nice Practical knowledge full work thank you

Really interesting video thank you for explaining this very clearly

[@sofiaaf1132]

Thanks for your explanation! That was awesome and I will for sure use it! Greetings from Costa Rica!

[@hatooor]

very nice video thank you very much this made me pass my chemistry assesments !!

[@ChemCampwithMrsNewman]

Congrats on passing your assessments!! So glad this video helped you ⚛️

[@DavidHarrisActor]

Very helpful. Thank you, Mrs. Newman.

[@ChemCampwithMrsNewman]

So happy you found this helpful!

This is really useful!

[@DavidRexGlenn]

Great video! Failed this section of chem class because I can't discern the difference between some of these colors. Still can't. Any chance of getting a video on making a pocket spectrograph?

[@EbuluChristabel-nc1ey]

It is nice.. i need the theory behind it

[@raccoonvallie]

I want to jump up to a higher energy level 🎉

Welcome!

Thank you it really helps to my assignment!

[@Kukiuui]

I have to memorise all colour for my competetive exam your video gives me a more practical look thus do not have to rote learn those colour now.. thanks miss :))) is there any vedio on borax bead test??

[@wearegonnadance]

That was very wonderful 🥰

[@ChemCampwithMrsNewman]

Glad you enjoyed it! Thank you!

[@Neylena]

could you soak these metals onto a candle wick overnight and then make candles and have the candle flame burn these colours!?

[@zasumi-z7n]

what materials did you used in this experiment?

[@ChemCampwithMrsNewman]

The solutions are made from deionized water and various ionic compounds (or salts) that have a cation that produces a color when placed in the flame. The most common tend to be Sodium Chloride, Lithium Chloride, Potassium Chloride, Strontium Chloride, Calcium Chloride, Barium Chloride, Copper (II) Chloride. Nitrate variations of these salts also work well. Hope this helps!

[@hey5051]

I WANNA ASK IS THE METAL LOOP WIRE UNREACTIVE ? ALSO CAN WE USE ETHANOL WHEN IT COMES TO ALLOWING THE SUBSTANCES TO STICK OR NO ?

[@zasumi-z7n]

how many wooden splint do you have in every glass vase?

[@ChemCampwithMrsNewman]

So I just put a handful in each vase. The number of wooden splints can always be adjusted based on need. If you run out, you can always add more.

[@AmandaCrosson]

I understand they emit light when they get de-excited, but how do they get de-excited if they are still being exposed to heat.

[@ChemCampwithMrsNewman]

So it would be similar to if you were to jump up in the air. You charge your legs with a certain amount of energy to jump up in the air but once there you can't stay there, you fall back to the ground. If you want to return to the air, you would need to jump again. The electron absorbs a certain quanta of energy and transitions to the appropriate energy level (an excited state) but would much rather return to its ground state energy level (in chemistry, the biggest driving force it for species to be able to achieve a the lowest possible energy state). So it releases the energy it absorbed to transition back. Once back at its ground state, it has the ability to absorb the energy again from the flame and transition again. This process is happening for not just one electron in one cation, but the a tremendous amount of electrons in a tremendous amount of cations in the sample of the ionic compound (1 mole of cations = 6.022 x 10^ 23 cations). Which keeps the flame colored. Hope this helps!

[@DorissaRadersma]

Great video and explanation. I have a classroom that doesn't have gas and would love to buy a set-up like you have in this video. I have been looking but have not seen anything like this offered. Could you point me in the right direction?

[@ChemCampwithMrsNewman]

Thank you! I found the burner on Amazon. I believe the link below should take you to it. Universal Propane Bunsen Burner www.amazon.com/dp/B091DJ9WHW?ref=ppx_pop_mob_ap_share

[@ChemCampwithMrsNewman]

The propane tank is a camping gas tank that can usually be found at a sporting goods store.

[@DorissaRadersma]

Thank you! You are awesome. Can't wait to be able to do these kinds of demos!! @@ChemCampwithMrsNewman

[@chinmayeesaikia6507]

Hii....What type of stick you were using here?

[@ChemCampwithMrsNewman]

Hi! They are called wooden splints. (Plain popsicle sticks can be used as well, they just may need to soak longer in the solution to see the color of the cation.) Hope this helps!

[@Trav_is_Newman]

Who’s that? That was nice of her!

[@adedejiadejoke2572]

Urgent Madam,would the wooden splint burnt with the flame test?

[@Trav_is_Newman]

The splint eventually burned. I think there is a time period where the solution burns off first though. You can see in the closeup shots if you look carefully. Ill ask her to weigh in too though.

[@ChemCampwithMrsNewman]

Yes, eventually the wooden splint will also burn. At first the splint is wet from soaking in the solution. The flame color is solely due to the cation in the solution. Once the splint dries out enough it will also ignite and there will also be a orange color present. So I always keep a waste beaker filled with water near by. When the splint ignites carefully place it in the water. Hope this helps!

Is it weird that I want to know what the other salts taste like? LoL I am assuming most aren't fit for human consumption though

[@wearegonnadance]

Same haha

[@woogieman02]

My son, 11 years old, is curious what would happen if you were to take two splints from different chemicals and burned them together. Been way to long since high school and college chemistry class for me to remember😅

[@ChemCampwithMrsNewman]

Excellent question! You should be able to see both colors in the flame. Hope he stays curious!
