Chapter 19, Problem 89IAE

The electrodes in the following electrochemical cell are connected to a voltmeter as shown The half-cell on the right contains a standard silver-silver chloride electrode (see Exercise 88) The half-cell on the left contains a silver electrode immersed in 100.0 mL of $\text{1}\text{.00}\times {\text{10}}^{-2}{\text{MAgNO}}_2$ (aq) A porous plug through which Ions can migrate separates the half-cells.

a. What is the initial reading or the voltmeter?
b. What is the voltmeter reading after 10.00 mL of 0.0100 M ${\text{K}}_{\text{2}}{\text{CrO}}_{\text{4}}$ has been added to the half-cell on the left and the mixture has been thoroughly stirred?
c. What is the voltmeter reading after 10.00 mL of 10.0 M ${\text{NH}}_2$ has been added to the half-eel described in part (b) and the mixture has been thoroughly stirred?
