The Zimmerman test for 17-ketosteroids uses which reagent, and what color indicates a positive result?

Explanation:
In this test, a strong acidic environment is used to react with 17-ketosteroids in the urine. The reagent employed is concentrated sulfuric acid. When 17-ketosteroids are present, this reaction produces a distinct purple color, which is taken as a positive result. If no ketosteroids are present, the mixture does not develop the purple color. So the purple color signals a positive Zimmermann test for 17-ketosteroids.
