thank you! studying for my finals tonight and this really helped!!!

Thank you so much! My chem teacher didn't have time to properly teach us and my book was no help. This, however, restarted my brain. ^^

thank you! you're so much better than my chemistry lecturer!

@Mieraz22 No mistake. The concentration of Ag+ is doubled because of stoichiometry. (When 1 unit of Ag2CrO4 dissolves, 2 individual Ag+ ions go into solution.) When writing equilibrium expressions, the concentration of each ion is raised to the power of its coefficient. Since the coefficient for Ag+ is 2, the concentration is squared. So, yes, the concentration is doubled AND the concentration of Ag+ is squared. All because its coefficient in the balanced equation is 2.

From what I remember from high school chem (aka I may be wrong) you just have to memorize the charges on certain common ions so that when you get something like Ag2CrO4, you know that the charge on CrO4 is -2 and the charge on Ag is +1, so then you know the neutral molecule splits into 2 atoms of silver and 1 CrO4 (+1, +1, -2).

wow this was so helpful, thanks so much!

This was suuuuuuper helpful. Thank you so much.

Thank you from Sweden!

Thank you. Really helpful.

Very gud video sir

Wow there hasnt been a comment on this in 6 years

Thanks! This was really helpful. :)

Thankyou :) Very helpful!

ur the best!!

@1006Will yea..me too.i'm confused.did he make a mistake or sumtin?

great!

ouhh.okay..get it now.thank you.^^

you didnt have to make an ice table....?

duuuuuud

dont get what your saying in the video at all

why is silver positive, u need to explain each concept not just say exactly what u r writing
