Title: Chemistry exp.
Post by: shubhamgh on July 04, 2021, 12:06:10 PM

Hello I am confused about the solution as how to solve the for the answer.

I found this but couldn't solve to get anything.

Ag/AgCl electrode is insoluble salt type electrode, here redox reaction of Ag takes place as

AgCl(s) + e– → Ag(s) + Cl–(aq). (1)

Also Ag falls below H in electrochemical series (+0.8 V vs SHE) and hence can behave as non- polarizable electrode i.e. its potential doesn't change by passing current through it so this type of electrodes can be used as reference electrodes

Do you know the Nernst equation?

What is concentration of Ag⁺ after addition of dichromate?
