Thank you so much sir... You have really helped me... I also like the way you talk while teaching
Thumbs up 🎉. You have 🪛 it well. God bless you 🙏
Great analysis
Great work teacher,, continue with the same spirit sir
Excellent job
That's great mwalimu... I really appreciate your goodwork
In adult school doing exams this year. Chem have been a challenging subject for me i wish i saw your channel way before😮, let me try to catch up.
Keep it up mwalimu....we are having similar goals.... Let us help tomorrow's generation
sure bro
A very nice lesson
Thank you sir talk about the confirmatory tests
Will do soon
Thanks sire
Great one mwalimu.
Nice 👍
😮
Good
😍😋
When testing for cations do u fucus but on the Na+\Cl-
Please sir when you add NaOH or NH3 to a solution what is forming the white ppt?
Both NaOH or NH3 solutions contain hydroxide ions.The ions react with cations forming insoluble hydroxides(precipitate) .
I think I like your chemistry mwalimu am chemistry teacher too
Thanks bwana Mbithi
And how would u now mk and analysis from that please sir when u add something like NaCl solution are u looking at the cation that is Na+ or the anion Cl-??
All sodium salts are soluble. Adding NaCl ,you look at Cl-. Can precipitate Pb2+ and Ag+
@@Mr.Kunguchemistry thanks sir
@@Mr.Kunguchemistry okk sir that means that the ones that are soluble u don't look at them right?
And then for anions do u focus on the one carrying the negativity charge or positive charge?
Anions react with cations. Anions are precipitated by positively charged ions (cations)
@@Mr.Kunguchemistry while cations are precipitated by negative charge ions?
Thanks sir
Correct
So sir when u add something like Pb nitrate to an unknown solution and a white ppt formed what do u think of?
Will u think of and anion or cation
Is it lead or nitrate that is reacting in solution to form the white ppt?
Nitrates cannot form a pot because all nitrates are soluble. Pb2+ can form a precipitate with Cl-,SO4 2-,CO3 2- & SO4 2-
in such a case you think about the salts of Pb that are insoluble eg PbX where X is the anion that will make the PbX to be insoluble
Pls sir are those all the reagents that can be used?
For the detection of cations?
These are the most common
Ok sir what of anions
There are a few more
