This video demonstrates the Lake Test, a critical confirmatory test used to identify the presence of aluminum in a salt mixture. The instructor explains the step-by-step chemical process, from preparing the aqueous solution to observing the characteristic white floating mass that confirms the presence of aluminum.
Hello students, today we are going to do the leak test. The leak test is very important.
It happens in the case of aluminum, meaning if you need to perform a CT scan on aluminum, it's confirmed.
You have to do the test, and only through the test is aluminum confirmed.
Today I will tell you exactly how to perform the lake test to confirm aluminum.
are your children giving you the mixture or salt, whatever is given to you
Okay, you need to take that salt mixture inside your test tube, okay? All right.
And then you have to make its OS, okay? So, if you have Salt Plus Water Loge, your OS will be ready.
It will be ready, right? Yes, it's ready now. This OS is all set. Now, what would you like to do in this OS?
You have to carefully observe this OS; you need to add blue litmus solution, okay?
So I have blue litmus solution here, okay? This is blue litmus solution.
What should I do with this? I'll add a little, just a small addition, okay?
Add a small amount of blue litmus solution, and add blue litmus solution
After this, add NH4OH to the test tube on this side.
Okay, then how do I add to the side of the test tube? Let me tell you.
Alright, exactly like this, start adding it to the side, just like the side
When you start adding Testib, you'll see something resembling a floating mass here.
Can you see a white-colored floating mass, or can't you see it? Who knows.
Alright, with this method, the white-colored floating mass will be visible to you, and this floating
In a month, if I try to show it to you even better, that's fine, wait a moment
A bit of tuning goes here, hmm
You will now see the white-colored floating mass, and this white color
The floating mass confirms that our colorless liquid is correct, right?
Aluminum has been confirmed here, okay? If you come across something like this
We get the white mass, okay, so it's precisely due to this white mass that we confirm it.
That aluminum is our confirmation, meaning this is C T four aluminum, and this
Test is also non-essential child lactates, okay. Thank you. See you next.
