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 concentraion of I-?
Please perform what you can and illustrate your work so I can follow. Thanks
Set up the relationship among the oxidative capacity of the heart muscle as well as the conversion of lactate that occurs there.
What volume of 0.10 M KMnO4 solution would be required to oxidize 20 mL of 0.10 M FeSO4 solution in acidic solution? Fe2+ is oxidized to Fe3+ and one of the reduction products is Mn+2.
This solution freezes at -0.159C calculate the degree of dissociation( the fraction of molecules dissociated) for the acid in this solution ( assume the mean ionic activity coefficient has a value of 1). c) from the dgree of dissociation determine..
