Smelling salts?

First

Thank you =)

In gemology, (precious gems) the refractometer we are trained to use utilizes reference "sodium" light, also used with hand held spectroscope (diffaction grating)

I winder how these currents are effected or to what degree if a strong magnet protected from excessive heat, is brought into proximity of a similar mass of molten copper and additionally to copper which is close to but not yet at its melting point

Great videos and nice chanell,,, My chemistry interest is spawned by my intrests in jewelry manufacturing and precious metals processing techniques, and from there dental metallurgy. An associate of mine had extensive knowledge of techniques for various electrochemistry methods for precious metals processing, i recall one time he described using tablets of "Sodium Boro Hydride" to precipitate gold in some methods. I always wondred how reactive is this material, and can it be safley used to inflate a baloon and how much lifting force of hydrogen would be released when one gram of Na[BH4]. I also wondered about its posible safe use for development of a tool for jewelers or technicians whereby a reaction canister could safely contain added feedstock and insitu generate hydrogen for a small jewelers torch. If you have any thoughts or decide to incorporate these points of interest into videos , ill watch for them. Thank you..

if in my procedure using KSCN the solution has a light red layer at the top and the normal colored solution at the bottom upon adding KSCN, should that be a positive result for Fe3+ ion in my unknown solution or would a completely blood red solution would have to form to confirm its presence?

mg vs petrole and diesel

Why is NaHCO3 needed and is its function in the reduction?

Excellent demonstration of the reduction of sulfate ions to sulfide by carbon thru the burning of matchstick. This microscale procedure is easy to perform.

Sir I'm contacting you gev me your number

10 out of 10 explanation, thanks a lot

Great pic Thanks

Thanks this is exactly what i wanted

Nice

So if you were oxidizing with potassium permanganate and acidic acid gently boiled together in water then allowed to cool in fridge with ipa to keep from over oxidizing then filtered with coffee filters /activated carbon in the filter to make a ketone alcohol how can you be sure to remove any manganese ions from the filtered liquid ?

Thanks for the video! i couldnt find anywhere the colour of a saturated I2 solution in water with no I- present except here

y la pregunta?

yo no pedi un yapuchino

Great explanation

Thank you.

Very Helpful 👍🏻

Awesome explanation. Thanks!

Thanks

puzzled for me for days of the 1/2 part! master piece explanation

❤️❤️

What is the concentration of the permanganate that you used please?

Thank u so much

Well..

this channel saved my ass in chem lab so many times. keep up the good work 🙏

Would the same thing happen if nitrogen or argon was in the tube? Does oxygen play a role in the reduction of copper oxide? Can copper chloride or sulfate be used instead of cuo?

Two questions about the reaction in basic conditions. 1. Why does the green colour even occur? The reaction to form MnO2 (s) should be a stronger reaction than the forming of MnO4 2- right? 2.. In your equation there is H+, but it is in basic conditions so there would be no H+. Am i correct? If so, my idea is that the reaction should be noted as: 3 MnO4 2- + 2 H2O --> MnO2 (s) + 2 MnO4- + 4 OH-

Can you name some other examples of exothermic reactions between carbon and metal oxides?

Best

I understand nothing, but this is so interesting!

Nice vid, great explanation. Totally unrelated, but you sound like Injustice 2 mobile youtuber Sigvald.

Great video, It's nice seeing someone making detailed and comprehensive explanations of foundational aspects of Chemistry. Someone will learn from this!

Dude thanks for your content. Can you also make some ZnS maybe with Mn or Ag doping and demonstrate their luminescent properties? Maybe just as this reaction in the video ZnO + S and heat :)

nice info men

Do you use this as a test for water contamination of hygroscopic reagents?

Another morning gift for chemistry lover

Sergai , you are amazing. I am chemistry teacher in India

Great sir, you spreading great experiment

Thanks for the demonstration.

This is so so amazing. Watching them practically gives life to your theory.

great explanation! Big thanks
