Hello students! Welcome to my channel
Chemistry Notes by Tri P
Today, first of all I wish you all
a Happy,
a peaceful, a prosperous,
a lovable
and a long living and welcoming
Happy Onam, from the bottom of my heart
This is quiet a different Onam for all Malayalis, mostly celebrated inside homes
Altogether a very different Onam as compared to our normal Onam celebrations
So once again, I'm wishing you all a HAPPY ONAM
So, today i'm going to take 9th grade CBSE

So in the last class we have studied
Suspension, Colloid and Tyndall effect
So, today we are going to study
Separating techniques. Like separating components of a mixture
There are 4 techniques for separating the mixtures.
 
First one, separating the coloured components from blue/black Ink.
Second one, separation of cream from milk.
Third one, separation of a mixture of 2 immiscible liquids.
and fourth one, separating a mixture of salt and ammonium chloride.
So these are today's portions.
So let's move on to first topic.
Separating the components of a mixture
These are the heterogeneous mixture, which can be
separated like these with physical method.
Like hand-picking, seewing
in our daily life.
But this techniques can be used only in some cases.
Only in some case like handpicking and seewing
like picking stones from the rice, sweeing etc.
But in some other cases we need to use some other techniques
So let's see some of these techniques for separation
First technique, how can we separate the coloured component, like dye
from blue/black Ink
Let's see how this is done.
For this activity we require a Beaker.
A beaker is needed
which should be half filled with water
Apart from beaker, the second thing is a watch glass
which is round in shape, which we can see it on labs,
a watch glass on the mouth of the beaker,
then few drops of  ink on the watch glass
So, today's class is over
and this is the occasion of Onam.
So enjoy Onam on these days
Also, as time permits, try to have a glance of subjects
so that u'r not lost touch with the subjects
It's a long one week gap, so keep in touch is an important point
so there is a possibility of forgetting as well as laziness can creep up
so do just have a rough glance on subjects in these days
So I hope, that you liked my class today
If so, pls don't forget to LIKE, SHARE and COMMENT
on my channel
So, let's meet on next class, next week
Till then, take care and thank you :)
let's see from today's class what we have understood/ followed
to check yourself
let's see a question
Just try to understand and answer it by yourself
and if possible, comment on the comment box
so, here is the question
Name the separation technique which you will apply for the separation of sodium  chloride from it's solution in water ?
So, this is today's question.
and give it a try...
