This Page is one of the best academic site I have ever come across. I’ll rate you guys 100 out of 100. I have watched your video on titration and now this… you guys are simply the best

[anneolurinde]

Thank you so very much sir. Y'all are a big help to students, for real. Keep up the good work 🙏💯

[EmmanuelLee]

Thanks so much Boss, so glad to have found this 7 hours before my exam😫🤲

I have an issue with when you added HCl to the residue. You are correct with the liberation of CO2. However, since you added HCl to PbCO3 there will also be the the formation of insoluble PbCl2 which dissolves on heating and reappears on cooling
To me HNO3 will be used instead of HCl.
This is likely to feature in the real exam

[BoseFashesin]

Thanks 😊 so much Sir
What are the component ions that are present in sample C30 Sir

[AshleyClark-nfev]

Thank you sir saw it 2hours before my exams

[EmmanuelJohnbull-hi]

I love how you broke it down, but residue + dil. Hcl+nh3 in drops wont give a gelatinous ppt.
So the observation should just be white ppt formed.
Once again thank you sir

[LoloJossy-mrnu]

Thanks sir
I really understood everything
Do more of physics and biology

[olaiwonbolanle]

This is the same thing know the yellow paper I guess❤. Thank you very much sir.

Try adding phenolphthalein to a solution of the residue. Solution turns pink. Confirmatory test for CO3^2-

[ugochioparaoha]

Why did I not find this video early enough to this examination.

[chinemeremopara]

Thank you sir....but i thought lead would give a white powdery precipitate....not white gelatinous precipitate

[osazeedosa]

Thank you sir but why isnt there a test for sodium to help identify the other inorganic salt(sodium carbonate)?

[JanetMichael-djvp]

Thank you sir
Sir how sure are you about the question coming out in this exam so that we'll not study the the table and the see a different thing in the exams.please don't disappoint us

[daniyanphilips]

Was FeSO4 and conc H2SO4 among the reagent?

[userIkechukwu]

After adding water to the mixture what would be observed is a white precipitate in a solution

[Uncle-Chemical]

Well done sir.
But you didn't add aqueous NH3 to the 2nd portion of the residue directly, rather, you added it to the solution from 3. Is it right to say 'residue + or solution 3 +... Also, element like Pb and Ca are not gelatinous but chalky, non-gelatinous or powdery.

[MustaphaCham-qybz]

Sir u are great
But will there be any theory lecture on your platform

[IjeomaEsther-esnm]

Excuse me sir,
I thought that they were only two cations that give white gelatinous precipitate i.e Zn and Al
Why is Pb also giving the white gelatinous precipitate.

[anyebesunnystar]

One question though… what does C represents in the first test taken?
