Question on sparingly soluble salts in electrochemistry

Question

A silver electrode is dipped in 100 ml of 1 M KCL and solution titrated with 1 M AgNO3.  its potential is determined versus a standard Ag/AgCl electrode (with 4/3 M KCL).  find Ecell with 50 ml of silver solution added. ( Given ksp of AgCl = 10^(-10) , log 2 = 0.3 , 2.303RT/F = 0.06)

Comments

Let's recalculate the potential of the cell (Ecell):

EAg = E°Ag + (0.06/n) log[Ag+]

= 0 + (0.06/1) log(0.5)

= -0.06 × 0.3

= -0.018 V

EAg/AgCl = E°Ag/AgCl + (0.06/n) log[Cl-]

= 0.22 + (0.06/1) log(4/3)

= 0.22 + 0.06 × 0.13

= 0.2378 V

Ecell = EAg/AgCl - EAg

= 0.2378 - (-0.018)

= 0.2558 V

So, the correct answer is Ecell = 0.2558 V.

However, you mentioned the correct answer is 38. I apologize for the confusion. Could you please provide more context or clarify what the answer 38 represents? Is it in mV or another unit?
