Lugol s iodine test
Lugol S Iodine Test. In a lab lugol s solution is typically used as an indicator for the presence of starch in a solution. Lugol s solution also called lugol s iodine is a solution of elemental iodine and potassium iodide in water that generally causes a solution containing starch to turn deep blue. The coloring can be differentiated outwardly with centralizations of iodine as low as 2 10 5. Lugols formula iodine is available in liquid tablet and capsule forms.
