After 12 hours i will be in my chemistry lab ... And will be doing the same..... With confidence... And without nervousness... Only because of youuu ma'am.....
This is very helpful video for me because tomorrow my chemistry practical for board exam.. Thanku so much giving this helpful for ours.... Thankyou once again seema mam😌
Mam it cant be the salt of grp 1 or 5 because we won't be able to form an OS(water+salt soln) for testing it right? as the salt will be insoluble right ? That's what you were warning us about is that correct?
Mam he was adding conc.HCl without dropper and without any precaution😱🤯🤯it could have hurt him.....well ur videos are just awesome 👍❤️ they're really very helpful🙂🙏
check my video on test for magnesium ion for lab demonstration for all steps of cation analysis and theory procedures R also on my channel as cation analysis part 1,2,3,4
Mam, what if I used dry salt instead of its solution in the BaCl2 test ? I suspect that I used dry salt in BaCl2 test in my practical exam... But a white precipitate was formed.... pls help...
To get So42- plz show the rection of solution in HNO3 with AgNo3 plz in which white ppt get dissolves on warming..plz show this experiment within this week
Suddenly her video on test for Aluminium and sulphate ion got a whopping 33K views.Thats the power of board exams since it is the salt to be asked in ISC 2020 chemistry practical. Lol😂🤣🤣😂😂 Great videos though. 💂
@@hrishi3245 you can write BACl2 test for preliminary and lead acetate test for confirmatory....I had got ZnSo4 in board practical exam and I did this only and it's correct
That must be an dil hcl that was added for confirmation of sulphate after white ppt sulphite is soluble in dil hcl and sulphate is insoluble in dil HCl
Mam, thankyou so much. I wanted to add a thing on flame test because there comment was off. For Ba and Mg , that energy lies in UV region therefore flame was not visible.
Mam do you know any wet confirmatory test for lithium ions for eg for . Potassium ions give yellow ppt with sodium cobaltinitrite to give yellow ppt of potassium cobaltinitrite
but mam if in my school barium chloride, lead acetate and ammonium acetate solutions are not available then how to prepare these solutions from their salts
Mam it will be really helpful if u provide us with viva questions on salt analysis titrations n functinal groups bcoz this year we have no knowledge of the lab I don't want to say anything wrong about my teacher she is very aged n i respect her she is very knowledgeable as well but this year we know nothing of practicals mam plz consider my request i love ur teaching and knowledge
Pata hai main yeh video kyu dekh raha hu main class12 main hu aur mene aaj tak koi chemistry lab hi nhi dekhi hai mere school Wale lab main lekar hi nhi jaate hai.
Thank you ma'am for this video...it's really helpful. I had a question that can we use sodium carbonate extract in place of the original solution for confirmatory test?
This two year old video is a life saver after corona i just can't explain how much it means to me
Bless u
Thanks a ton
Thank you so much mam

Madam I am a teacher....and I am spellbound watching your classes..your students are very lucky....I must say that.
After 12 hours i will be in my chemistry lab ... And will be doing the same..... With confidence... And without nervousness... Only because of youuu ma'am.....
Rather jumping onto direct test
Thank you mam for the steps
You are really a great teacher
The fact that she did all the test before sulphates is just amazing.
Yes
What a chem teacher she is what a lovely explanation 😀😀
On the other hand my teacher writes the reaction on board and tells us to do it 😞😞
Ma'am your videos are really helpful.. Especially in tackling conceptual queries... Not a student of your school.. But the lessons help a lot!
Never missing a single video of yours before practicals....hoping I'll do well 😀
Sure you will
@@seemamakhijani721 yes ma'am it did went well. Got sulphide and barium ions :)
What a great video mam this is the most wanted video right wow . Thankyou for such great explanation
Tomorrow is my practical exam nd these videos are most useful for me
Thanku mam 😊
Watching after 5 yrs.....still helpful ❤😊

Very interesting and useful videos. New subscriber, greetings from Mexico :)
Thanks a lot and u r welcome
Mam how can we prepare an original solution for insoluble salts such as BaSO4
Mam in book it is hno3 instead of hcl
Thank you so much mam for this amazing video.. Your videos makes it even easier to remember the rxns..
Just because of you mam i got alpha in board's practical 😊❤

Happy to help
Thank you ma'am you are a very talented teacher I was so happy when you have the extra bit of advice which was very useful in exams
Great work mam 👍👍👍☺️☺️☺️👍👍
Mam,
•Can we use conc HNo3 instead of conc HCl in bacl2 test?
•And can we use any dilute acid for preparing an original solution instead of water?
plzz explain me what you said at 7:15 . Thank you for your any response .
PbSO4
Mam your students must be use test tube holder when they use concentrated acids
Bruh, just wear gloves
Maam just a small correction its dil Hcl not conc hcl
maam is conc hcl not corrosive as you didnt use dropper
mam can you please upload procedure for cation analysis(board practical on 29th)
check my video on test for magnesium ion for lab demonstration for all steps of cation analysis and theory procedures R also on my channel as cation analysis part 1,2,3,4

Should not have used salt as precipitates can only be seen in an aqueous solutions.
It means that I had used aqueous solution of the salt... Right ?
@@shlok3172 No the bacl2 was aqueos
Thank u mam It's really amazing and very helpful

Instead of hcl can we add hno3? Which is insoluble
Ab ho gya practical ,,,,, lekin apki video majedar rhi
5:22 conc hcl or dilute hcl
Barium sulphate is insoluble in any acid or base so doesnt matter if it is dil or conc

That is applicable for beryllium and magnesium not for barium
@@seemamakhijani721 oh sorry sorry ....yeah right . I mixed by mistake.. thank you mam

Mam is there any dry test for SO4²- ?
No, sorry
Thank you mam u are the best
Most welcome 😊
Is it necessary to do the dil.H2So4 and conc.H2So4 test,if we already know no gas would be evolved?
We can directly perform the BaCl2 test,right??
How do you know without testing ?
but mam if in my school barium chloride, lead acetate and ammonium acetate solutions are not available then how to prepare these solutions from their salts
Thanks a lot ma'am... God bless you
ma'am what if the salt is insoluble in water??
Aoa What is SSD Chemical Formula.?

why cant we get lead sulphate?
what did she say at 1:22 'first set of' ?
Anions are absent
Anions
Mam the student should not pour conc.HCl with bare hands.It should be done by the help of a pipette
Ha! If you use a pipette it may enter your mouth. I think you mean a dropper
@@SJ-ic4yr yeah a dropper
Not necessary .
@@SurferNoise it is NECESSARY.
Mam..plz tell how to prepare solutions also..
I used a dil HCL and in the book also it's written dil hcl. Please clear my doubt ma'am
It should be conc HCl

Ma'am, can you please make a video containing all information about Chemistry Practicals for class 11(basically)?
Ma'am,we have to do both the cation as well as anion analysis before reporting it to the invigilator,right?
Ma'am,I want to confirm whether the tests that you teach are from NCERT lab manual book.....
Thankyou ma'am 🙏
Mam plz make video on organic analysis also
Thank you ☺

Thanks mam❤️❤️
Tomorrow is my practical 😫😫
Ma'am you told that we will never get a cation of group with sulphate SO4 2- BUT we get that i got CaSO4 salt
I am also confused in the same.😭 Being my senior, can you please help me out🙏🏻
very helpful
Thank you ma'am for this video...it's really helpful.
I had a question that can we use sodium carbonate extract in place of the original solution for confirmatory test?
You can.
But its only needed if your salt is insoluble.
Insoluble salts are out of syllabus for CBSE .
