nothing like a last minute cram on the bus before my practical exam , cheers bro :)
Your way of explaining these complex thing is so good , that they appear damn easier. You are too good man ! (Y)
Very helpful!!! I did these experiments along with a few others, but I had a lot of troubles. After review over the tests, and then watching your videos I understand things A LOT more, which will be helpful for when we have to find an unknown anion. Thank you!
Awesome video, described quick and simple! Thank you!!
Your explanation is incredible
Love your method of explaining.
Thank you! My professor required this and the cation flowchart as an assignment before we start our lab tomorrow. I am so glad I found your videos because I have never done a flowchart and have never seen these. Saved my life haha.
this helped so much, thanks!
Good video, really understood everything.
This totally helped me for my test.. good job :)
this is really helpful for revision, helps me to visualise it thank s
great work..... keep doing... and keep helping us
thanks sir. A great presentation and helped a lot
Great presentation
Great video. Have shared with my friends :)
very much helpful and simple to understand...
god bless
I dont know who you are, but i will look for your videos, like them and subscribe. Thank you so much! This video really helped :D
Can we also use bacl to test for sulphate?
Is there a glow chart for this like the cations test
Why we acidify medium with HNO3 before adding AgNO3 when testing halides?
thank you very much for helping me in my lab report!
Thanks it was helpful and well explained. By the way can you maybe make a tutorial about polymers used in industrial chemistry?
for sulfate ions, don't you add barium chloride rather than barium nitrate or are they interchangeable?
Why did we swap from mixing stuff with HCl to HNO3 to get the H+? Also why are we mixing stuff with acid in the first place?
Thanks this helps for my O-lvl's chem
How do we know what medium the solution should be in,acidic or alkalic?
Complex ion can be AlO2- or Al(OH)4- ?just wondering?
nice job, neatly done..
Hello! May I ask u that why the testing of anions need an acidified medium?what is the reaction of the acid with testing solutions? How does the acids remove the interfering ions? Thank u!!
sir, can u explain how to test nitrate ion using copper chips and using some ring test.
Jeslin Joseph its not in cambridge syllabus
My textbook says that a white precipitate is formed which is soluble in dilute HCl. (CO3)
Thank you so much!
your explanation is fantastic clear and identify the important point ✨✨✔👌
Really very helpful thank u sir..
thank u sooo much because of this lesson i was able get good knowledge so thanxxxxxzzz a lot
@Kuga Pol OK. Please subscribe and stay tuned!
THANK YOU SOO MUCHH!!. My chemistry teacher is really bad at explaining so this is my only way of learning now ;-;
Why need to add equal amount of strong acid on it ect HCl/HNO3/H2SO4???
what is the use of hcl acid?
Awesome Tutorial
Thank you :)
Awesome.. Thank you
Thank you
quick! how do we tell which solution is soluble and insoluble i think its related to transparency but its not clear to me can someone explain please?
If it dissolves in NH4Cl... It is soluble...and if not it is insoluble... Please correct me if I m wrong
5.24
"if bromide is president"
Why is it a must to start with acid? Can u make video explaining that!
Thanks.
+Tapa Adding an acid helps to eliminate the possibility of other anions. e.g and acid + a carbonate produces effervescence, while there's no immediate reaction if an acid was added say to a sulphate.
You saved my exams dude
thankyou so much:)
nice but i think u should also add the ionic equation
Thanks so much
Am now better in that
Awesome
thankyou
nyc explanation
so2 also turns lime water to milky white. ????
Yep. But SO2 will turn ac. K2Cr2O7 green or ac. KMnO4 colourless, which CO2 won't .
Alexxx i need helpp
not clear for nitrate ion.
the comments convinced me to watch this video
haada molhey k liyan
this is a mess
