How to differentiate between the cathode and anode in these kind of questions where single compartment cell is used where salt bridge isn't mentioned too and since we have every part that is the metal ag the salt agcl and chloride ion on HCl would we treat the cathodic part as metal insoluble electrode i got this confusion as the compartments aren't mentioned so do we just take the chloride here from HCl to full fill conditions for metal insoluble electrode ?

In th cell representation

#

Anode is in left

#

And cathode at right

#

Always

#

And for single compartment

#

This particular cell we know ag has +ve reduction

#

So based off that

#

We have to get

turbid oasis
#

I get that but when salt bridge isn't mentioned and how can we decide HCl goes in the cathode or anode as it changes the answer of question

south lava
#

So whether the other reaction is feasible or not will decide

turbid oasis
turbid oasis
#

Anode I mean

south lava
#

Say for example we have some reaction which is non spontaneous

turbid oasis
#

Isnt that going to be data based

south lava
#

Then hydrogen will be cathode

south lava

south lava
#

It does yh

turbid oasis
#

So u mean HCl is part of both anode cathode reaction as it's a single compartment ?

#

Then only it makes sense

south lava
#

Nah nah

#

I mean that take 2 different scenarios

turbid oasis
south lava
#

Where once say we have cr3+ to cr

#

Which is non spontaneous

turbid oasis
#

Like once cathode would be metal metal ion and once metal insoluble

south lava
#

Here the hydrogen electrodes will act as cathode

south lava
south lava
#

Here the reaction is spontaneous

#

So the hydrogen will act as anoden

turbid oasis
south lava
#

Well then

#

Wht I am saying basically here is

#

Deciding wheather hydrogen is anode or cathode will depend on what is the other substance with it

#

Like in this question

#

It is ag

#

Which goes to ag from ag+

#

Which is a spontaneous

#

So yaha par hydrogen anode ho jaayega

#

To give a +ve cell

turbid oasis
#

😭

turbid oasis
#

I get your point

south lava
#

I mean i would suggest

#

Kuch common electrode

#

Yaad karlo

#

+ve ya -ve

#

If you can

turbid oasis
#

Yyp I know for zn ag cu

south lava
#

😭😭

#

Too common a

#

Aur bhi hai

#

Ag

#

Cr

#

Oxalate

#

Br

turbid oasis
#

But humare usulo ke khilaaf hai data yaad rakhna class mai badi debate hoti hai

south lava
#

Cu

south lava
#

Bas +ve ya -ve

#

See if you want to you can

#

Baki it's upto you

turbid oasis
# south lava Bas +ve ya -ve

Yeah that toh I know complete series and from where it is positive and negative but it's considered bad to not go by exact info given in question like questions in advanced are framed such you won't need extra info from anywhere

south lava
#

Hn to that much is enough

turbid oasis
#

And don't you use the general electrodes like metal insoluble and so on

south lava
#

To me all of them are same

turbid oasis
#

You would miss out on the solubility product terms and formation constant terms

#

Or is it not used that much in NEET ?

south lava
south lava
turbid oasis
south lava
#

It's alright

south lava
turbid oasis
# south lava I would say trust this always

Yeah ik but we are used to remember through salt bridge and single compartment aren't exactly the part of jee but I get it that you can solve it through standard potential data idea

#

Any ways thanks

south lava
#

In the end both gives u answer

turbid oasis
#

Yup right
