Problem 78AE
An experiment was designed to determine whether an aquatic plant absorbed iodide ion from water. Iodine-131 (t1/2 = 8.02 days) was added as a tracer, in the form of iodide ion, to a tank containing the plants. The initial activity of a 1.00-μ L sample of the water was 214 counts per minute. After 30 days the level of activity in a 1.00-μL sample was 15.7 counts per minute. Did the plants absorb iodide from the water?
