The experiment is amazing. Thank you.

You only use one solution until you finish the table

Wow that's great 👍 thank you

I don't know why this channel is not active 😢. Sir your way of teaching is very heart warming. Otherwise I have learnt something big in combiing gas volume ls😊

Helpful

Very, thanks for orgnizing such a

On strong heating it melts to form a white sticky mass which gives of steamy vapours on heating more strongly the white residue gives off reddish brown fumes which turns moist blue litmus paper red the residue is pale yellow when hot and on cooling it changes into white colour

thanks a lot manze

The second reading and the third reading did you still fill the burret to be up to 0

Definitivamente lo recomendaré Gracias! Hasta en el español se entiende

Reddish brown fumes of nitrogen dioxide is evolved

😊😊

Do one need to change also the base for the second and the third titration

So helpful 🎉

you made it so easy to understand🔥🔥🔥

Best experiment inhave ever watched loved ot

0:42 yeah me too Yeah me too Yeah me too

You should do more of calculation that is where the challenge is

it is black

Two decimal places is preferable for the titre values obtained

Observation: original colour- white ,colour change- turns yellow on strong heating ,gas evolved-(water vapour(initial))No2 reddish brown,O2colourless , residue- zinc oxide is formed yellow-hot ,white-cold.

thankyou

CuSO4 in the presence of strong heating gives us CaO black color substance and sulphur dioxide gas which is an acidic gas and oxygen

Tq sir

How about placing the sodium metal into liquid oxygen?

Laughing gas

Isn't NO2 poisonous?😐 You are letting it out

What is the change in it physical or chemical??

Thank u😇

Ratio 2:1

Icse - Platinum electrodes💀💀

thanks for the stop watch reading sir, it helped me to write practicle notebook. thank you very much

When zinc hydroxide is heated ot decomposes to form zinc oxide and stream (chemical change). The residual zinc oxide is yellow when hot and white when cold(physical change). Zn(OH)2=ZnO+H2O ZnO(cold and white)=ZnO(hot and yellow)😊

Wonderful

2H2O ---> 2H2O+O2

Thank you sir lots of love and respect from India 💙

Great

hello, i thought u were gonna use a diluted stock solution and mix with the required NaOH solution inorder to get an accurate dilution result

Good work show more and back titration also organic chemistry 1and2 with practical

I bet you used Sulphuric Acid H2SO4 to acidify the water. The two electrodes are obviously decomposing the H2SO4 resulting in the two gasses H & O being collected. Show me water being split without using an electrolyte which contains H & O.

really helpfull...exams in 2 hours and i think i will do well:)

thank you sir.. love you from sri lanka.. 🧡

Oxygen

NH4NO3=N2O+2H20

N2O gas or nitrous oxide

Cool

Thanks I hope I remember it.....I have my cse exams soon

I need other expt

Love from India 🇮🇳
