Hi all there. Again I am preparing another inorganic salt. I hope I will use it to titrate a pottasium permanganate solution in a future video.

Your videos are amazing!! So relaxing at 4.00am in the morning. I love watching science videos late at night and your videos are right up my street. Beautiful!!
Thank you! Even though that video is old and many things have changed in my style since then hehe. Appreciate the comment
Very interesting !!! Congratulations !!!
It is always good to make mohre salt.
Amazing video! Thank you so much
Thank you¡¡¡ If you like it check out my other chemistry videos¡¡ :D
Amatőr!
Your experiments are amazing, exactly the same as I have done. Very helpful, but when filtering it should use a glass funnel
Yeah this video is pretty old, back in the begining of the channel haha. I invite you to visit my last videos, im sure you will like them ;)
It was very helpful to me...thanks for making...☺
+Indu Kapila Thanks to you for watching :D
Hi, I want to know how much Mohr's salt do you obtained. Thanks and great video again !
Hi Science K! At the moment of filming that video I didnt even have a balance so... No idea of yields and weights at all. But this is a pretty easy crystallisation and high yields are expected :D
@@Glattuh okay, thank you 👍
How long did it take the crystals to form? (for example in days)
That particular clip took a few hours only, since they are form by recrystallization from hot solution.
Why does the iron(II)sulfate- solution need to be hot during filtration?
Hi! The point of that is to decrease the volume and so increase the concentration in hot conditions. All of that is done in order to purify it by crystallization from hot solution method. You can also leave it and let it evaporate if that is the question too. The crystalls grow much better (in terms of purity) when they grow slowly but for my video the method I used was more than enough, and also for time saving ;)
Thanks for the question :)
I thought that mohr's salt is supposed to be pinkish purplish?
Well normally iron salts are green-blue (iron II) and brown (iron III). Maybe you are thinking in a manganese II chloride wich is white pink or even a permanganate wich is very strong purple.
Chemsitry dont lies, my crystalls are blue-green as expected :D
Thanks for commenting ;)
Hola, un par de recomendaciones:
1. Los clavos vienen galvanizados, mejor utiliza clavos que se vean oxidados por fuera
2. siempre mantén un exceso de H2SO4
Funcionó igual de bien con los clavos que use. Me di cuenta de mi error con el ácido sulfúrico y lo corregí, en el video se ve.
Igualmente gracias por la aportación.
Un saludo ;)
is that tiesto in the beginning lol?
+blip boop Yes it is ;D
Can you explain the calculations a bit better?
