In higher class when you will go then you will learn that water is not neutral .it is both acidic and basic in nature not simultaneously but depends on the property of other reactant, in short it is of an amphoteric nature
Its been 4 years, so many things has changed but still useful for students and will be useful for future students as well! A big salute to Alakh Sir!🙏❤

Sir u have a lot of knowledge in u . U are really very superb no one can teach like u. You have cleared my all doubts.actually when I studied my chapter I had doubt that from where this ammonia gets basic nature due to lone pair. Thnx very much.

Hello bachhon. Hi sir. Aap bhut achha pdha rhe hai. Bas do rectification karni hai, pehle to vaccum nhi hota, vacuum hota hai. Dusra ki inverted funnel paani ke surface tak hi hona chahiye, paani ke andar nhi, taaki air gap bn sake.. Thankuuu 😀

Sir jb *ammonia* ko *phosphorus pentoxide* se *dry krte h* to uska reaction aisa hota h :
*6NH3 + P2O5 +3H2O =2(NH4)3PO4*
Sir isme *water v reactant q hai* ??
👏 people before 11 march
4:42 sir here is exception for nitrite and nitrate salt
sir in the last equation you did
NO+O² - NO²
I think it'll be
NO+O² - 2NO²
2NO+O2=2NO2
Which alkali is used in prep of ammonia?
Calcium hydroxide.
Why?
Because •it is cheap•it is not deliquescent
Which drying agent is used to dry Ammonia?
CaO
Why?
Because it is basic in nature it doesn't react with ammonia.
How is ammonia gas collected?
By downward displacement of air.
Why?
•Lighter than air
•Highly soluble in water.
Why is the ratio of alkali uaed is higher?
To compensate the loss of ammonium salt (ammonium chloride)by sublimation.
Can we use ammonium nitrate for lab prep of ammonium?
No.
Why?
•it is highly explosive.
•decomposes to form N2O.
What about Ammonium nitride?
No.
Why?
Decomposes to give Nitrogen N2.
Why is the flask tilted in lab prep of ammonia?
So that the water vapour formed in the reaction does not trickle back otherwise the heated glass apparatus may break.
Thanks
We all have a reason to see this video. Thank you sir for your explanation.
B'coz only of dis man I start loving chemistry ❤️💯
