The iodide (i2) content of a commercial mineral water was measured by two methods that produced wildly different results.6 method a found 0.23 milligrams of i2 per liter (mg/l) and method b found 0.009 mg/l. when mn21 was added to the water, the i2con- tent found by method a increased each time that more mn21 was added, but results from method b were unchanged. which of the terms to understand describes what is occurring in these measurements? explain your answer. which result is more reliable?
