pH
i am not getting the way as to how to approach these type of questions(73) where u just get the initial conc. and not the ka value and the que is asking for ph

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.what i tried and some random scribbling in end
Have you seen that alpha equals root k by C vala relation
That has some name too I guess
I'll show wait
c alpha square = kc
ostwald dilution law
Uhh I see ruko
This should be common ion effect ka question
mybe
Let me scribble a bit
Ruko
kyunki h dono acid denge
yh
Some data seems insufficient for some reason
we need the ka imo
@iTeachChem
Help needed sir
uhm kya kre
diya to itna hi hai
Hmm sochta hun
If I get something
phenol weak acid hai
I’ll reply here only
Yeah I know
uska disscoiation kam hoga to almost negligible hoga ion ka
aise kar sakte?
Hmm ph to nikal jayegi
vahi chiye bas
Pho minus ki concentration kaise nikaloge par
maine ye last wala chiz kbhi try nhi kiya
aise karti
vahi to bolri iska kam hoga na bahut conc kyunki dissociate bahut kam hoga
To usko calculate to karna padega na
Question me bola hai
hnn vo to hai
Kitna kam par
Vo baat bhi hai na
Chalo mai khana khaane jaa raha
par ph nika sakta haina iske bina bhi? ya usme bhi significant rahega ion ka conc
Aake dekhta hun ise
hn
Ph to HF decide karega
Phenol se thoda sa farak aayega
Won’t matter much
hf ka jaise nikal gya bina ka ke
inorganic breaks me 🙂
HF is very strong
When compared to phenol
🙂
pka highly negative
does this work here ??
hn to agr neglect kiya bhi minus to bhi ka uski dissociation ho jana jo almost inital conc hogi
usko karlo to bhi ph sahi ayega?
i havent revised pc in a long time so might be wrong
We don’t have ka
Thats the issue
Your formula uses it
ka nhi haina
oHHH
And your formula is for weak acid plus weak acid
both are weak ...
Hamare case me weak acid plus strong acid hai
HF is way stronger buddy
i legit just googled if HF is a weak acid
Huh?
oh this might be in water ig
Not as weak though
hf is strong
phenol se kafi jyda
ys kyunki vo water ke sath vapis HF bana leta hai
Google ke AI pe mat bharosa karo pls
Uska pka google karo
Kitna negative hai
oh damn
3.2 hai
acidic
3.2
Still not as low as I expected
phenol ka somethin 6 tha shyd
Phenol se bohot Kam hai par
Yeah
no its 10
wth
how is it acid
explains i guess why phenoxide ion is so basic
73 sir
Not 72
sir not sacchrine one i did tht one nicely
73 is my doubt
"acidic character"
And
Organic acids are anyways weak
ypp true
phenol wala chp yaad aya
yea you need to take Ka values from literature
Reaction nahi hogi?
PhOH + HF ---> PhO- + [HF]2+
i think zumdahl says this
Or am I missing smthing
Volume nahi diya h par
and only HF matters i think
(for H+)
HF is also a weak acid tho?
🤔
Alcohol se strong hoga yeah
once you get H+ then back calculate the phenoxide ion conc
But
yea 10^-4 vs 10^-10
Yea
HF ka Ka needed hai tab
Aise nahi hoga
for phenoxide you do common ion effect
Yea
yea both ka chahiye
Ka
HF to get H+
Not exactly
It's still stronger than most organic acids
phenol to get phenoxide ion
Yus
This is done then I guess
You do need ka basically
kinda but here the Ka values are not comparable, they are orders of magnitude diff
True
As we said
It's a strong vs weak acid comparison
yes in comparison 1 will always be weaker than the other :0
:)
whole of oc is based on this lol
Lmao true
But as you said
"comparable differences"
kyu hoga?
ahh okkk
Bruh nahi hoga ye
vshi to
Dono me se koi bhi proton gain nahi karega
Dono lose karenge
apas me kyu react hoga
exact
Nahi hoga
hn ik
khair this is done ill get the ka values and solve it
Yup nice
yhh
