Common Ion effect

Both the statements should be correct in this one right?

Note for OP

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's turbidity
Why would common ion cause precipitation

reaction backward jaaegi

DexterOP•1/9/25, 2:58 PM

Ya dono sahi hai

DexterOP•1/9/25, 2:58 PM

ya dono galat

DexterOP•1/9/25, 2:58 PM

Wait

DexterOP•1/9/25, 2:58 PM

is BaCl2 a ppt?

DDexter is BaCl2 a ppt?

iTeachChem•1/9/25, 2:59 PM

Yes.

IiTeachChem Yes.

DexterOP•1/9/25, 2:59 PM

google says no

DDexter google says no😿

iTeachChem•1/9/25, 2:59 PM

True. Checked. 36 g / 100 mL

DexterOP•1/9/25, 2:59 PM

yeah wahi ba

DexterOP•1/9/25, 2:59 PM

iTeachChem•1/9/25, 2:59 PM

BaSO4 is ppt

DexterOP•1/9/25, 2:59 PM

we use it in Volumetric analysis

DDexter we use it in Volumetric analysis

DexterOP•1/9/25, 2:59 PM

BaCl2

DexterOP•1/9/25, 3:00 PM

Usse hi to sulphate ka test karte hai

IiTeachChem True. Checked. 36 g / 100 mL

DexterOP•1/9/25, 3:00 PM

Yeah

DexterOP•1/9/25, 3:00 PM

what to do now

DexterOP•1/9/25, 3:00 PM

answer is given 1st correct second incorrect

iTeachChem•1/9/25, 3:01 PM

Both have same solubility

iTeachChem•1/9/25, 3:01 PM

But yea in terms of mol /l bacl2 will be smaller.

IiTeachChem Both have same solubility

DexterOP•1/9/25, 3:02 PM

Crazy lmao

iTeachChem•1/9/25, 3:02 PM

Cos mass of BaCl2 is higher.

iTeachChem•1/9/25, 3:02 PM

And also 1:2 salt.

iTeachChem•1/9/25, 3:02 PM

Check if this is there in lab manual somewhere.

IiTeachChem Check if this is there in lab manual somewhere.

DexterOP•1/9/25, 3:02 PM

Lemme see

DexterOP•1/9/25, 3:04 PM

kahan dekhu but
Huge lab manual

DexterOP•1/9/25, 3:04 PM

Cl ka test dekhta hu

DexterOP•1/9/25, 3:05 PM

nahi hai Cl- ke tests mein

DDexter nahi hai Cl- ke tests mein

who am i ?•1/9/25, 3:10 PM

check in sulphate ion test

who am i ?•1/9/25, 3:11 PM

bacl2 test is confirmatory test for sulphate

DexterOP•1/9/25, 3:27 PM

ruko ek second

DexterOP•1/9/25, 3:27 PM

iske baare mein kuch nahi likha hai

DexterOP•1/9/25, 3:27 PM

just the reaction

DDexter ruko ek second

Gamertug•1/9/25, 9:19 PM

Statement 1 is true

Gamertug•1/9/25, 9:19 PM

statement 2 will be false

Gamertug•1/9/25, 9:19 PM

common ion will aply in 1

Gamertug•1/9/25, 9:20 PM

cuz BaCl2 dissociates weakly

Gamertug•1/9/25, 9:20 PM

but it wont be in 2

Gamertug•1/9/25, 9:20 PM

becuz NaCl is strongly dissociated

GGamertug cuz BaCl2 dissociates weakly

iTeachChem•1/10/25, 12:43 AM

Why do we say this? Solubility agar high hai then it dissociates completely na

iTeachChem•1/10/25, 12:47 AM

My initial guess was this too.

iTeachChem•1/10/25, 12:48 AM

But the weird thing is wiki says solubility is 35 g /100 ml.

iTeachChem•1/10/25, 12:48 AM

But ksp value is 10 ^ -9?

iTeachChem•1/10/25, 12:48 AM

From the second data it is clear that one is true and two is false (what we initially said)

iTeachChem•1/10/25, 12:49 AM

Anyway. Yea check lab manual and / or ncert equilibrium chapter. Whatever that says we can go with for jee.
