A voltaic cell operating under standard conditions (1.0 M ion concentrations) utilizes the following reaction: Cr(s) + 3 Ag (aq) → Cr "(aq) + 3 Ag(s) Which of the multiple choices correctly describes how the cell emf changes when a change is made to the cell? Ca) Adding water to the anode compartment makes the cell emf less positive. C b) Increasing the size of the silver electrode makes the cell emf stay the same. C C) Adding a solution af 1.0 M AGNO, to the cathode compartment makes the cell emf more negative. C d) Adding Na,s to the anode compartment to precipitate chromium suifide makes the cell emf less positive. C e) Adding a solution of 5 M Ag* to the cathode compartment makes the cell emf stay the same.

Question
A voltaic cell operating under standard conditions (1.0 M ion concentrations) utilizes the following reaction:
Cr(s) + 3 Ag*(aq) → Cr³*(aq) + 3 Ag(s)
Which of the multiple choices correctly describes how the cell emf changes when a change is made to the cell?
Ca) Adding water to the anode compartment makes the cell emf less positive.
C b) Increasing the size of the silver electrode makes the cell emf stay the same.
C C) Adding a solution of 1.0 M AGNO, to the cathode compartment makes the cell emf more negative.
C d) Adding Na,s to the anode compartment to precipitate chromium sulfide makes the cell emf less positive.
Ce) Adding a solution of 5 M Ag* to the cathode compartment makes the cell emf stay the same.
