Chemical equilibrium with real examples

In this video two experiments showing the chemical equilibrium and the law of mass action are explained.

Finally, a video with actual demonstrations instead of just a bunch of talk and calculations to melt your brain

I once made a Nitrogen dioxide equilibrium jar back when I started chemistry. I kept it all the way up until a few weeks ago. It stayed with me through moving houses two times. When I finally tried opening it, it had sealed itself and I had to destroy the lid of the jar. Good to see you back, my friend!

Awesome video! Exactly what I need for my chemistry exam!

[mananambaliya]

thank you sir performing experiments makes us more clear about the topic of equilibrium

How many milliliters was your Fe(SCN)3 solution diluted into before being poured into the 3 test tubes? 2:50

[MarvynG]

What is the middle beaker 3:47 in the video? Is it a total equilibrium, with the other 2 beakers favoring reactants on the right and products on the left?

What a great video . I'm chemistry edu student from Indonesia. Thanks for the explanation sir. I really need this. I'd like to use your video as a reference for my final project. Hope you don't mind about it. Thank you.

Can you explain why dinitrogen dioxide is a not existent molecule?

[primeamv]

What were the materials used in the experiment?

[venndiagram]

however subsequently after adding the FeCl3 to KSCN and letting the solution sit, wouldnt there be significant iron hydrolysis as well? So would the solution need to be acidified in order to prevent the formation of ferric hydroxide. Could you advise me on how I should go about conducting this experimenting so that I may avoid this problem. thank you!

Lovely. Thanks for this. I will have to use the thiocyanate one: I don't have a good demo to show the effect of the stoichiometric coefficients: at least I didn't until now.

[jesscorbin]

So, it's absorbing heat at the beginning right

[krishlian]

What's the clear liquid where 10 ml of both solutions were added?

[jasonwilliams]

Hi im a student with a chemistry for the IB program and was wondering where you got the nitrogen dioxide for this experiment?

[ShroomLab]

I always wondered how one measures the concentrations

[nicktohzyu]

you can use Audacity to remove noise from the audio, it's a free software

[marcochiarini]

very nice demonstration ! for sure not something intuitive still you see it with your eyes

[BadPete]

Iron(III) and thiocyanate makes complex ions. [Fe(III)(SCN)]++ -ion makes the color.
