@gusty notch

[jolly goblet]

i was able to figure theres involvement of two electrons in the redox rxn

[jolly goblet]

yeah thats where am struggling
hg2(no3)2 or hgno3

like hg2 2+ hoga hg2+

what -

[jolly goblet]

this is my coaching module lol

[jolly goblet]

alrrr

can u also help with the 2nd part

3b

[jolly goblet]

can u link the video pls

[gusty notch]

try kar na

do line likh eq ki

and make k thingies

[gusty notch]

this is an uphill task

xD

Fo 3b, we are asked to find the Ksp of Ag2CrO4 and for this we need the concentration of Ag+ ion which is the anode of the solution
To find the concentration of Ag+ anode, we are given EMF of the cell and we have two half cell rxns
Ag -> Ag+ anode + e
Ag+ cathode + e -> Ag
So, the net cell rxn comes as
Ag+ cathode -> Ag+ anode
From this rxn, we find the reaction quotient and substitute the values in Nernst's equation
Also, note that we have same electrodes, so E°cell is going to be zero

[gusty notch]

what is the conc of Ag+ in this ksp equilibrium - that yo ucan find? usi se you get ksp backtrack kar ke

same hi hai what you have to do in the previous q tbh

[gusty notch]

well done.

yea it is a conc cell too.

[jolly goblet]

ohh got it

thanx ppl
