Common Ion Effect

Adding more chloride ions to a saturated solution of potassium chloride produces iridescent crystals.

[@MimiTachiwkawa]

great for visual learners

[@RodrigoNAlvarezF]

Thanks! I was looking just for this kind of experiment.

[@likhiveesa]

Seriously ! , He is the Real Teacher

[@jaweriasiddiqui2193]

wonderful explanation.

[@noonesland2471]

amazing work! thanks!

[@MonkeyDLuffy-xr4fl]

Thank you!

[@mr.waheedaljazoli1612]

Very nice, thank you

[@user-ih6dr5jf5s]

Thanks for explanation ❤️❤️

[@thayhuongchuyenhoalekhietq6803]

Thanks a lot! Great video.

[@sajidakamal8284]

Thank you so much

[@jyothsnapotnuru4932]

Thank you sir

[@pritamdas3456]

Ahh nice!!! theory learning with practical experience . !!!!!!

[@86shally]

On left hand side of first equation, it should be KCl (s) rather than KCl (aq.) sir

[@mynameisambertoo7379]

No, it’s within water so it’s aqueous

[@methodfortytwo4308]

Greatest explanation ever

[@yashitabawane]

THANK YOU :-)

[@razmossis]

Why didn't the 4/5m solution precipitate though?

[@johnamarnath8004]

Thanks a lot

[@irfupedia8829]

what is the solution PH

[@risingchemistry7434]

Wonderful

[@valekhya]

Thanks ! :)

[@KashafNaeem.]

How can we know which compound is more strong in exam?

[@sharad9176]

Thank you

[@SarveshKumar-ml5jd]

Great

[@skeche]

the super safe old guy talks about adding the common ion chloride from NaCl to a water solution already with KCl and explains that due to Le Chat's priniple, adding stress will cause the equiplibirum to shift the stress to counterbalance the change. So we see an excess of KCl which is in the reverse direction, indicated by the crystal forming.. but why is he pointing at the KCl in (aq)? should that be in (s) for solid?

[@paterfamiliasgeminusiv4623]

Good point but i think it was hcl not nacl.

[@Rahulkumar-vc9vd]

Good point

[@mynameisambertoo7379]

It’s because it’s in water, making the compound aqueous.

[@Isekaitruckdriver]

ty sir.

[@oz93666]

Good work ! But you describe the process as a 'Reaction' is this strictly accurate? Nothing reacts with anything , the increase in chloride ions just 'pushes' the KCl out of solution...

[@sohamawargand8678]

🔥🔥🔥

[@movie_fan_cuts]

This will be surely asked for ur chem practical for viva..thank me later

[@Olivefromthere]

Malayali huh

[@kiranprasad2191]

12 molar HCl 😱😱😱 wow!!!

[@upendrababu5888]

Nuvvu thop mamma

[@khalifahvidal3959]

no gloves and no fume hood but excellent video sir

[@crossfadez5521]

probably because the reaction is quite safe.

[@rampalchauhan7819]

Wow😎

[@waterbottle-]

you are goddamm right

[@rgz0videos899]

Tnq so much sir tomo i hace chemi exam 😘😍😍😍

[@hotarouoreki3463]

Why didn't he wear gloves

[@madhavanmarikani3313]

Experience

[@user-nq5ps8og1l]

Le chatliers principle simplified

[@adityawidnyana727]

Gua kesini cumn mindai buku di intan pariwara

[@user-mj1oz6mq6h]

اللي من طرف استاذ شادي لايك 😁❤️

[@faridabano344]

his surname is 'gross'.
just kidding 😅

[@dreamcatcher3805]

Malayali undo ❤

[@slayergaming3727]

😌

[@vinaysingh6605]

Thanks sir

[@MuhammadSameerAliAnsari]

Great

[@Burnguy21]

thank you sir
