Do we have to learn all or selected?
How we can learn all?
Bro once I tried to learn the colours ..
I repeated them ...
Red yellow green violet blue oxidising reducing.....
After some time (mere dimag ki batti jali )..
I thought ...What am I doing ????
And began to laugh on myself...
So final result... No one can learn it...
If their is trick please do share.
NCERT mein bus cobalt ka diya tha in s block.
I asked about the same to my chem teacher.He simply told the chances of then coming are really low.
And,If you want to only see the ones given in NCERT.(In between the chapters).
As told by my prof, there's no need to learn the colours in all temp range.
only learn the colours of ALL in the mid or cold temp range.
also , borax bead test gives the colour of that veri cation(the characterstic one)
ni - brown
cu - blue etc.
