Posted on March 25, 2022 By music_admin The Marquis Reagent is a commonly used chemical reagent testing kit. It is made from sulphuric acid and is extremely strong, so it should be handled with care. Moreover, it can cause severe burns to the skin, clothing, eyes, and mouth. To avoid these harmful reactions, it is best to wear latex gloves when handling the reagents. After testing, dispose of used reagents in baking soda.
To use Marquis Reagent testing kits , you need to place a tiny amount of the drug on a white ceramic blotter. This amount of powder is about the size of a matchstick head or a grain of rice. Remove the cap and tilt the bottle until you see the drop falls out. It will take between 30 to 60 seconds for the color to change. Be sure not to touch the tip of the bottle, or else the drug will not come out.
