You are literally a life saviour on god. May god bless you for blessing us with this content. I wish you were my teacher I wouldn’t be crying my eyes out for a chem test. Thank you sir! respect.
Ive been trying to understand this topic for like a year now and I never got it but now my finals are coming up and in just 20 minutes you made me understand a concept that I didn't understand in a year thank you so much
I have a chemistry WA3 tmr, and I couldn’t understand preparation of salts well, but your video helped me a lot!! Thank you teacher for the clear explanations! 😇
Yes the formula of nitric acid is HNO₃, but the ‘2’ is called a coefficient, it is used to balance the chemical equation. When writing chemical equations, we need to ensure the same number of atoms on each side of the arrow. This is due to the conservation of mass.
Group 1 salts refer to any salt of Group 1 metals, such as sodium chloride, potassium sulfate etc. Ammonium salts are salts containing the ammonium ion, such as ammonium chloride, ammonium sulfate or ammonium nitrate.
Some sources will refer to aqueous ammonia as ammonium hydroxide. The reason why aqueous ammonia is preferred is because ammonia is a weak alkali, which only partially dissociates in water. At the molecular level, most would exist as ammonia molecules instead of ammonium and hydroxide ions.

Bro this video was absolutely amazing, i have understood the most difficult chapter of chemistry in less than 20 minutes, thanks again bro
nice! It’s very encouraging to hear that :)
I watched this video during my igcse exams 3 years ago and now I'm watching it again for my ials. I love this sm best explanation yet
Thank you so much!! I never understood this lesson until I came across your video, and that flowchart omg it summarizes the whole thing!

best of luck for your WA3!
Wow mahn, this video really opened me up, thanks a bunch
I have my chemistry final on Tuesday and considering the fact that I find Salts a bit hard, this video did alot to make me feel better about it.
THANK YOU SO MUCH!!! SPECTACULAR, CONCISE, AND IMMACULATE! Keep up the amazing work sir!
great to hear that, thanks for the comment! 😊

You erased my confusion! Thanks alot
I’m happy to hear that, best of luck for your chem test!
@@MrJansenTan 😊
YOU ARE AMAZING. honestly better than my chemistry teacher . thank youu
Thank you! This video wass soo helpful
VERY helpful 👍
Thanks. But nitric acid formula is HNO3 but in most equations its written 2HNO3. Can you please explain this
Yes the formula of nitric acid is HNO₃, but the ‘2’ is called a coefficient, it is used to balance the chemical equation. When writing chemical equations, we need to ensure the same number of atoms on each side of the arrow. This is due to the conservation of mass.
Perfect video!!! 🙏
Bro this was amazing
thanks u soooooooooo much, u are amazing
this video is great thank you so much !!
Marvellous 😋😍😘🤩
Bravo
For making silver chloride, why do we need sodium chloride? Will HCl work?
any solution containing chloride ions would work, hence HCl can also be used
@@MrJansenTan ok thanks a lot!
Thank you!!!!!!
thank you!!!
what is the meaning of Y and N in the (soluble) column on your first slide.Hope you reply to this soon.
Y = Yes (soluble in water)
N = No (insoluble in water)
tysm
Thank you so so much
Why are you so underrated ☹️
What is group 1 and ammonium salt ?
Group 1 salts refer to any salt of Group 1 metals, such as sodium chloride, potassium sulfate etc. Ammonium salts are salts containing the ammonium ion, such as ammonium chloride, ammonium sulfate or ammonium nitrate.
better than my stupid teacher powr lah mr jansen tan
thanks a million sirr
Omgg thanks so much!
I thought aqueous ammonia is NH4OH
Some sources will refer to aqueous ammonia as ammonium hydroxide. The reason why aqueous ammonia is preferred is because ammonia is a weak alkali, which only partially dissociates in water. At the molecular level, most would exist as ammonia molecules instead of ammonium and hydroxide ions.
@@MrJansenTan I see thanks
ngee ann 3r4 student was here
Any 3R5 ppl here ?
