The coordination number is the number of lone pairs around the central atom. If something is attached to a bidentate ligand, it's coordination number is 2 even though there is only 1 ligand.

Bruh you guys released the full videos I LUV YOUUUU

For those wondering how transition metal/complex (precipitates) form, it's when the complex has a net zero charge, so a solid forms, if it is charged then it dissolves into solution.

I love u

10:45 the state symbol for [Cr(H2O)6]^3+ should be aq not s

[@myfccs]

Yea

[@naemibe6174]

OCR says that Cr(NH3)6 is a purple solution and Cr(OH)6 is a dark green solution. You guys say the (NH3)6 is dark green....

[@haziqibrahim2994]

9:29 , the chromium hydroxide should be Cr, right?

[@freezeburn1]

13:24 Carbon 🅱️onoxide

[@mayonnaise7547]

In the textbook it says that the colour change goes from violet to purple

[@zethayn]

Thank you for the whole series! It helped me a lot.

[@obviouslewiscarrollreferen7928]

When you add a little ammonia to an excess of positive ligand, at first it acts as a base and forms however many NH4+s as there is positive charge on the initial ligand(e.g. Cr(H2O)6[3+] as green solution forms green precipitate of Cr(OH)3(H20)3[0+] as 3NH4+ is formed. This is also true of Cu(H2O)6[2+] as a blue solution which forms a blue precipitate of Cu(OH)2(H2O)4[0+] and 2NH4+s

13:24 "carbon bonoxide"

[@RAHMANISHMIL]

i need a video on ionisation energy please

[@nimrababar6621]

Very well explained. Good work

[@nurlatifahmohdnor8939]

This topic is hard. Student need to refer to visualize.
I will read for them so that they will get very familiar with is-ti-lah.

[@2mrRB]

Great video! Which ligand exchange takes place to substitute the oxygen at the places where it is needed? Which other ligands are often used in the human body to substitute it with the functional ligand?

[@victoryohikhena7895]

Thanks a lot for the videos
They are really insigthful
Truly snaprevise

[@moiethereal9634]

Thank you so much for this. by the way is this chem playlist the full contnet of chemistry

[@snaprevise]

[@tapkoang]

Very helpful videos tutorials. Thank you sir

[@asharkhan1942]

Love you guys for such a great pleasure..❤️❤️😘

[@arshithgowda8728]

Advanced

[@jalajarora2331]

Is this AS or A2 chemistry???

[@LeahRebecca]

Jalaj Arora a2

[@jalajarora2331]

@@LeahRebecca ok thanks 😀

[@janani1826]

although it is a2, some schools may do it at as because it is one of the first a2 topics( I am in year 12 and doing it right now)

[@sashajanczyk3811]

Shame; good videos, but most of the comments just point out mistakes you guys made. Good job tho.
