For example, if I give you a salt containing group 3, how would you identify it?
How the hell will you know, dude, that it's group 3?
So you'll start from the beginning, like how do you conduct group analysis?
If white precipitate (PPT) forms with OS plus dilute HCl, it's positive; if no precipitate forms, perform Group 2 test?
If you get Group 2, it's fine; meaning, you'll get the black PPT. If not, you'll have to move to the top of Group 3.
What's in group 3 now? You have to take the OS.
So, I'll take a little bit of salt first, and then I'll dissolve it in water, so give me enough water to dissolve it.
Now, if we have to carry out testing using this OS, what are you saying? Tell me clearly—do you mean we need to take the OS and what exactly do we need to install on it?
NH4OH and NH4Cl will act as buffers.
And what shall we hide afterward? NH4OH
I will pour NH4OH into the beaker.
As I added NH4OH here, you can see white gelatinous precipitate forming.
Is it not white? Is it not white? The white jelly? The white color? Everyone can see it, right? Okay?
