How do you make a 10% solution of iodine?
To do this, note that iodide is 0.769 times the total KI present, the ratio of atomic weights of iodine to potassium. Then, [I + KI(0.769)]/ml = the concentration of iodine. 16.9 gr/(16.9 gr + 33.7 gr + 118 ml) = 0.10 or (10 %) A similar calculation can be performed for the strong iodine tincture.
