Precipitation Reactions - Using the Solubility Rules

- Basic idea of precipitation reactions. NOTE: when working with precipitation reactions, the solubility rules for ionic compounds are used to determine if a precipitate forms or not.

My left ear really enjoyed this
?
lmao relatable (only if u wear headphones)
LMAO
its so awkward how much better this guy is than my actual teacher who has way more resources
10/10
In response to you your name: i did
Liam Copich dammit liam!!XD
do u give ur teacher handies in the closet
Ben--I have watched about two hours' worth of videos explaining precipitation reactions, aqueous solutions, net ionic equations, and so on. Yours is by far--and I mean by FAR!--the clearest and easiest to understand, with the most well-laid out and clarified examples. Thank you so much!
Thanks Luke. Means the world to read such a kind comment!
without your videos i would not be passing chem! thank you!
Bless your soul, soooo helpful!!
Thanks so much! I'm having the hardest time in Chemistry, and I've been having to look up a lot of "How to" videos. Thanks for making things simple and easy to understand! :]
I had no idea how precipitation reactions worked before watching this video, pretty darn confident now, god bless you, sir.
Its now 2018 and this video has still proven to be useful thanks
Thank you soooooo much. DO NOT stop making these videos.
Great video. You made what seemed a very complex part of the chapter very straightforward, easy, and fun. Thank you.
Thank you so much! Your explanation is so clear.
that was a huge help !!
THANK GOD FOR THIS VIDEO
you mean to say thank ben. and his chem videos
***** hahaha true
+Marco Hernandez ben is god
This makes so much sense! Thank you.
OMGOSH YOU ARE AMAZING, I HAVE A TEXT ON TUESDAY AND THANKS TO YOU I AM SO CONFIDENT! !!!! THANKS 👍👍👍
This was such a big help! Thank you!
Thank you. Greatly appreciate the clear explanations and colors. Finally Got!!!
Best explanation!
MAN YOU ARE THE BEST!!! THANKS!!
your videos are very helpful for my chemistry midterm tomorrow. thanks, bud :)
This video is the exact video i am looking for! :D
Thanks Ben! You're still helping students 9 years later! Very helpful!
Thank you for your kind words, and thanks for watching! 😀
Thanks so much better than my science teacher
This helped a lot! Thank you!!!
Thanks man. Helped me BIG TIME!
Oh my gosh thank you thank you thank you
4 teachers and multiple friends have tried to explain this to me and didn't succeed but in a short 10m you did!
you're the best. thanks so much for these videos.
Thank you!! This video helped a lot!
Thank you. I finally understand precipitate much better
you just saved me. Thank you!
Awesome, thanks! Taking chem online and have to learn on my own from the book (tests are done in person on campus but everything else is on our own) and was having a lot of trouble understanding what I was reading. This has helped clear up a lot of my confusion.
Thanks Ben, u are the man
Thanku so much, you make it seem so easy, and yes our teacher is making us memorize that hold chart, along with limiting reactant problems, and finding the emperical formulas from the limiting reactant, and oxidation-reduction rules, not to mention all of the Gas Laws. Some body please pray for me and my classmates!!! But i thankyou for helping me with a clear understanding of precipitaion reactions. Sorry for the paragraph but i had to vent to someone lol
Thank you sir! You saved my exam :))
thanks a lot.. ive seen your other videos and they're really helpful!
Thanks for this. It helped me. I have a reporting in our chem. class tomorrow and I need to discuss this and double displacement reaction. If not for this video, I wouldn't understand precipitation reaction.
Great video. Very helpful!
Thank you thank you thank you!
Thanks for the help.
Thank a lot ser!
Very helpful! Thanks!
This is excellent. thank you
I really appreciate these study aids. Thank you for investing your time to make this!
Are you there ?
Thanks for being a cool dude and uploading this.
thankyou so much.. i actually understand now
Super .... Your voice is bold.
Thanks very much for uploading this video. It helped me with my take home exam.
Thank you!
THANK YOU SIRRR !
Thank you so much!!! Had to identify precipitates on my test without even being taught the solubility rules! Looked up a ton of videos and was losing hope until I stumbled across yours. By far, the absolute best!!!! Thanks so much from India!!!
You're very welcome! Thanks so much for your kind words 😀
Appreciate it. Very helpful.
Thanks for throwing me this life jacket...
This helped me soo much thank you
Thank you!!!
Lifesaver!
Great video
YOU ARE AWESOME
Awesome vid
THANkS SO MUCH!!!!!
THANK YOU!!!!!!!!
very informative
thank you!
thanks ben
Test tomorrow and don't even need to read notes on this..... U explained in 10
Great! :)) thanks much.
thank you
THANK YOU!!!!!!!!!! Anyone reading this, WATCH THIS VIDEO, he explains it well!
You're very welcome! Thanks for watching 😀
thank the lord i uderstood since im writing chem tomorro
Great vid :)
OMG I GET IT!!!!! MIND BLOOWWWNNNNNNNNNNN
Very good 👍 👍 txxx
Top man
Wow thx alot
Thanks man :-)
excellent
Thanks a lot, I would say you did better than my teacher that toke two class to explain all of that.
You're very welcome 😃
thank you :) hopefully on the day of my exam(which is tomorrow) I won't forget!!
+LittleMixOf1D DId you pass lol?
awesome! I understood EVERYTHING so CLEAR!! I wish you were my teacher:)!
Hey ! You there still now ?
thanks
Thanks man
Great video
Amazing explanation
Examples were very helpful
You're very welcome! Thank you for your kind words! 😀
@@BensChemVideos wouldn't have said it if I didn't mean it
Seriously helped a lot
Thank you
nice video
If you look at the periodic table of the elements, whatever column that the element is in correlates if it is positive or negative.
good...
ty :)
finally understood something tnx
You're very welcome 😀
Many thanks, my parents included.
If I pass my chem 103 test today I'm subscribing.
You're the best man!!
I wanted to ask from that last question that's Na2SO4 + KCl. When switching how come that so4 doesn't come first and having to determine if it is aqueous or not. Should it be So4K(aq)?
Would it be possible for you to do a video(if you have not already) on writing a balanced formula equation, complete ionic equation, and writing a net ionic equation? I am learning it in class, and I am totally and completely lost
Water is a liquid, so we use (l). Soluble ionic compounds dissociate in water, so we use (aq) for aqueous. Insoluble ionic compounds do not dissociate in water, so we use (s) for solid. Even if an ionic compound is soluble, if it's not in water then it's usually a solid at room temperature, in which case (s) would be appropriate.
why did you swap the NO3 and the Br and how do we know whether it is to be swapped or not?
QUESTION!!!!! doesn't the last equation 9:55 have to balance yet? Since it isn't balanced will that affect the outcome? I don't see how it would. IDK
Just a small mistake, for the final equation on 10:27, there should be 2 moles of KCl and 2 moles of NaCl so that it balances out the equation. You need to have 2 K, 2 Cl, and 2 Na on both sides for it to be balanced.
Is there an easy way to remember the rules. Because in an exam they won't be giving you a clue or any rule sheet. Or do we just have to dead set remember them?
If the compound has a group 1 element is it automatically soluble ?
Why do the pairs switch in the reactions? As in, why are the cations of the reactants paired with the anions they weren't with initially, for the products? Sorry if my question is unclear but this is something I am having trouble understanding.
Molly Koch Its a chemical reaction called Double Displacement.
thank you Jesus for you man
No, because Na is a 1+ charge and there's two of them, and Cl is ALWAYS diatomic (which means it exists in two) and also has a 1+ charge. So Na2Cl2 is just NaCl. :)
Why the concentrations of the two solution in a precipitation reactions are different?
