Molecular, complete ionic, and net ionic equations | AP Chemistry | Khan Academy

In the molecular equation for a reaction, all of the reactants and products are represented as neutral molecules (even soluble ionic compounds and strong acids). In the complete ionic equation, soluble ionic compounds and strong acids are rewritten as dissociated ions. In the net ionic equation, any ions that do not participate in the reaction (called spectator ions) are excluded. As a result, the net ionic equation shows only the species that are actually involved in the chemical reaction. View more lessons or practice this subject at www.khanacademy.org/science/a...

this was put in the simplest form to clearly understand. I though it would be too difficult but I get it, thank you so much!
lol you know every material from every courses
That moment when a free video is more clear and easy to understand than a $200 book. I am looking at you pearson. >.>

@@netcald991 Many textbooks are that expensive. It's easy to imagine, and if you go to college, you'll likely need to buy such books. A harsh reality that will hopefully change by then, but definitely true. They really do cost that much, if not more, especially if you're buying them new.

I am literally doing this exact equation currently so this was so helpful 😂
Thanks, Khan Academy
Khan is better at teaching students than the teachers teaching us. No cap 😌🖐🏽
I'm taking Chemistry 104 currently and got a final exam tomorrow and thus is gonna be partial apart of it. So I appreciate this vid.

This was very helpful, thank you so much.
concise and helpful
My Chem teacher told me your channel for a clearer understanding and thank God she told me because i finally understand how to balance chemical equations along with the Ionic. Thank you sooo much❤️
How do you know all this? Thank you so much for making my educational life much easier.
Today’s my test! Thanks a lot!
Wait this is the best explanation I’ve seen so far, thank you so much!
I understand after this topic so well after a 5 minute video yet somehow not from a whole lesson from my teacher...thank God for Khan Academy🙏
Thank you I now understand how to do this.
Final question In the article "precipitation gravimetry"I would like to know balanced equation
Helpfull 🙏🏼 Thanks
yo thanks so much, i need at least a 75 on this chem test
Nice and simple ty!
No need for fancy words, I always deeply thank you for your videos. You make my day.
Very helpful. Thx a lot
how do you identify the spectator ions
Thank you for the video, but the main bits of information are lacking - for example, how do you allocate charges?
Thanks so much
Bruhhh this is so helpful . Tysm !!
Ho' my god I have to learn this at one point 💀
do chlorine ions not form molecules with themselves?
thanks this helped alot
Did a way better job at explaining than my chemistry teacher did.
How do i figure out what is aq and what is not? Ive balanced an equation to 2NaOH + CuSO4 -> Na2SO4 + Cu(OH)2 But now I need to write a net ionic equation but I cant figure out how to determine spectators without knowing its solubility

thank you!
What do you do if no solid can be formed? Or is that not possible?
@_elommusk

If there's no solid, I believe you still only do the molecular equation and complete ionic equation, but no net ionic equation.
Thank you so much
the fact that I'm not sleep 2 minutes into the video proves you're better than my teacher😄
is this video on the khanacademy website as well?

Copper carbonate and hcl plz tel ionic equation
Why did u not split the 2 at the end of the equation
@RedLtdGuitar
5 жыл бұрын
If you mean why he didn't split the AgCl, my understanding is that it forms into a precipitate (hence the (s) for solid) and therefore, you don't write it as individual ions. But, the sodium nitrate is still in an aqueous state and therefore, you write those two things as Na^+(aq) + No3^-(aq). Someone correct me if I'm wrong!
Technical correction: The original equation is called a Formula Equation, not a Molecular Equation (as it contains no molecules).
I'm stuck on how you know if the element has a positive or a negative

metals form positive ions, non metals form negative ions. If it's in group 1 of the periodic table it forms 1+ ions, if it's in group 2, it forms 2+ ions, group 3 is 3+, group 5 is 3-, group 6 is 2-, and group 7 is 1-. The transition metals are slightly different cos they can form multiple ions, but the question should tell u using Roman numerals, eg Fe(II) forms 2+, and Fe(III) forms 3+, hope this helped :)

Right, same.
Should give a little bit more difficult problem to work on, such as one with subscripts and brackets, etc....This was too easy.
In my experience, Kahn academy has only every made things long and complicated. After years of being forced to watch their videos, and deciding their methods were just not for me, a teacher assigned this video saying it made everything make sense. It made more sense before I was in chemistry at this point. No thanks Kahn academy.
