thanks for all your "How to Write the Formula" vidoes, it really helps for my chemistry work and helps me understand how to write the formulas on my own
Awesome. Sir it is a huge request to make a brief video on a 3-electron bond(where we represent 3 electrons above a covalent bond like in the case of NO) which is somewhat mentioned in Linus Pauling's book.And if possible do consider the Singlet linkage theory
I don't think you'll find H+ on the solubility table but Cl- is there. Since HCl is a strong acid it will dissociate completely in water so it is soluble.
It really depends on the concentration. The HCl is used in the video was less than 1. But if you dilute it enough it could be anything below 7. Strong acid just means that it dissociates completely in water.
How concentrated does the HCl need to be? I'm trying to get a piece of zinc stuck in my graphite crucible out and toilet bowl cleaner (9.5%) hardly moved it.
In this video it's pretty concentrated. I actually used muriatic acid from home depot. But really, if you wait long enough I could expect the 9.5% to do it, just at a slower pace.
@@wbreslyn I left it overnight. By the way after I posted that I got it out. The HCl apparently ate the rim enough that I could (with great force) slide it out.
@@wbreslyn I melt pennies by the way to pour into various molds. It always leaves behind some stuff, mostly zinc oxides I would imagine and possibly the copper coatings which is probably why HCl hardly dented it.
@@ThePeterDislikeShow Yeah, agreed, likely some coating slowing things down. I have used conc HCl to eat the Zinc outside of pennies. Very satisfying: ruclips.net/user/shortsvJswbN5_O94
I used concentrated in the watch glass and then in the flask it was about 6M. So fairly strong. But the reaction works with less concentrated solutions, just not as vigorous.

You're very welcome!
Thank Dr. B! I'm having my chemistry exam today and video experiment will come in clutch.
All the best on your exam tomorrow!
If ur in 10th congratulations u just learned the most easy equation of the syllabus
@@fuzial4659 It's not about the equation, it's about the visual memory you get from the video😀
Great explanation, I love it!
Excellent!
Thanks Dr.B! ❤

I am watching from Bangladesh.🇧🇩
Thanks for showing it so directly
My pleasure 😊
i appreciate the assignment answers
Hey!!
Nice that your channel is expanding from just text to real reactions!
Do more!!!!
They are certainly more fun to create but take much, much longer. But I do hope to do more!
Does Clemmensen reduction require amalgamation of zinc with mercury salt?
Thats sick Dr. B I'm a 8th graders and I love watching practicals
Yeah, this was a fun one to do! Glad you enjoyed it too.
Thanks Dr. B!😊
I got a B+ because of you :)
Excellent!
👍🏻 nice! So if i check a solubility table , i should see that H an Cl are soluble in in H2O?
I don't think you'll find H+ on the solubility table but Cl- is there. Since HCl is a strong acid it will dissociate completely in water so it is soluble.
@@wbreslyn so being a strong acid HCl must have a pH

I used as flux for iron soldering on aluminium
Awesome.
Thanks!
yo !!! nice expirement :D Dr B

@@wbreslyn Is there a way to dissolve the copper but leave the zinc intact? I make zinc art and that would make the zinc melt a lot more cleanly.
What is the colour of ZnCl2 after reaction??
It's soluble so it is dissolved in the water. So no color really.
❤️❤️❤️
Thanks!
what was the PH of HCl ?
I used concentrated in the watch glass and then in the flask it was about 6M. So fairly strong. But the reaction works with less concentrated solutions, just not as vigorous.
