The concentration of a potassium iodide solution can be determined by first adding excess silver nitrate: i'(aq) + ag+ (aq) → agl(s) the excess silver ion remaining in solution is then determined by reaction with a potassium thiocyanate (kscn) solution of known concentration: ag (aq) + scn(aq) → agscn(s) in an experiment, 50.00 ml of 0.0565 m agno3 was added to 25.00 ml of a potassium iodide solution. it then took 8.32 ml of 0.0510 m kscn solution to precipitate the unreacted silver ions. what is the concentration of the original ki solution?
