water
pani ka buisness isme smaj nhi aaya like 300 ml pani me 50 ml hcl aur 20 ml hno3 dala ya sab mix karke usse 300 mil kiya ya individually kaise?

Stay hydrated guys
jaari hydrate hone
iska batao
Jokes apart
Calculate concentrations just the way you do
Like go volume by volume terms
And then do the usual business
Agar nahi work kar raha to mai dekhta hun when I get hold of pen paper (jaa raha bas lab vahi pada hai)
Got something?
Ohnoionic
Doesn't seem like it much lmao
It's the easy stuff
Hydrolysis is the real deal
(Imo)
are pani kya kaisa hai kuch smj nhi aaya
kitna ml hai
1000 ml ka solution banana hai
hn
Solutes bata diye usne
hn ml me
Baaki bacha paani
Uski jarurat bhi nahi padegi imo
Concentrations nikaal ke dekho
If the numbers make sense to neglect karke kaam chal jayega
thk try karti
(water ki baat kar raha)
hnn
Damn shit
I just read the full question
It is kinda good
I thought it was something very generic
i am not able to do the conc thingy
i am getting weird conc.
like very low in hcl and very high in hno3
Then we'd be neglecting the H+ we are getting from HCl I guess
i dont know if my calc is right though
the water buisness is confusing me
i will revisit this que at night
This is what I've done until now
Yeah it's just tricky calculation
Nothing very special about it jo tumhe na pata ho
Just playing with concentration terms a bit
yh but it confusing a bit
Yeah I understand
Btw poora question bhejna to
What are required to find?
Vo dikh nahi raha
yahi hai pura
H+ and OH-
conc
Ohh haan shit hai to sahi
and the ph
Sorry ohkay
npp
Vo 65 vaale se confuse kar liya
Light sa colour tha dikha nahi lmao
isnt 50 ml the vol of solute , and density relates to vol of solvent so how we use this eqn
Density solution ki hai na poore?
hn
aur soln me to dono hai hcl and hno3
how can we just use tht
Tab to this valid
Dono ka separately kar lo
We just need the mass
Ki kitne grams water aa raha hai
Kitne grams HCl, HNO3
let me try
and total water 930 ml hoga na ? cuz rest is solute
Nahi
HCl HNO3 bahar se add kar rahe hain na
Vo uski bahar ki density hai
Usse calculate karke you just get "weights"
Ki kitne grams HCl+H20 daala
ok to jo given density hai vo conc hcl ke 50 ml soln ki hai right?
Yeah exactly
Ye fact kaam nahi aayega 'cause molarity me vaise hi solution ka volume aata hai
Solvent ka alag se required nahi hoga
aa this que is confuing
But yeah it's correct
Dw chill
Move ahead
Maybe look at this later with a calmer mind
hn this yh
but i thought maybe yw weight nikalne me kaam aaye
At such instances switching subjects helps
Vo pehle se nikal jayega
maut ke muh me jaane ka smy aa gya lagta hai
phy karenge
Hume bas HCl or HNO3 ka weight chahiye technically
okk
Riyal karo jaake lmao
thik ill revisit this after phy
Ngl physics meri bohot weak ho gayi hai for some reason
(that some reason is doing chem all the time)
me rn
yea it is equivalent to giving their molarity.
So you are adding 38 g HCL/100 g soln x (1.19 g soln/1 ml soln) x 50 ml soln = 22.61 g HCl
Similarly, 70/100 x 1.42 x 20 = 19.88 g HNO3
volume becomes 300 + 20 + 50, which is then made up to 1 L
so, you have 22.61/36.5 mol H+ from HCl, 19.88/63 mol H+ from HNO3 (these are mol of the species, each is monobasic, so same as mol of H+)
[H+] will be 0.935 in 1 L soln
share caln na? main thing is to always write units like i have done above
mole concept hai
sir vahi smaj nhi aara as to what values to take the water buisness is confusing

Jo maine upar dala did that make sense to you?
yh that made some things clear so i think t will try this question again in a few
