Problem- A solution of I- gives 301.0 mV in a cell with an iodide ion selective electrode. 10.0 mL of the solution is mixed with 3.00 mL of 1.00 x10^-6 M AgNO3, and the Ag is completely precipitated as AgI. The cell then gives 310.2 mV. Assume the electrode has an ideal Nernstian slope for I- at 25 C. what was the original concentration of I-
