WHAT ARE REAGENTS?

Reagents are chemicals that change colour when they come into contact with certain drugs, enabling y'all to detect their presence in a sample. Reagents cannot, nonetheless, detect every drug, nor can they tell you lot how pure or potent your drugs are. Fifty-fifty if you get the expected color reactions for the drug yous desire, there could still be i or more other drugs nowadays. This is considering:

Not all drugs change color with reagents.
Darker colors may overshadow lighter colors.
A very tiny quantity of a drug may not produce a visible color modify.

Despite these limitations, reagent testing is useful for identifying the presence of specific drugs, and——most importantly——for determining whether your sample does not comprise the drug yous want.

REAGENTS CAN

Detect the presence of certain drugs
Inform your decision well-nigh whether or not to consume a drug

REAGENTS CANNOT

Tell you how stiff your drugs are
Tell you if your drugs are pure

HOW TO USE REAGENTS?

one reagent-test-kits-visuals Identify a tiny amount of your drug onto a white, ceramic plate. Make it near the size of a pinhead. We will refer to this every bit the "sample" of your drug. For pressed pills, use a sharp knife to scrape the powder off the side. For blotter paper, cut off a tiny slice of the corner. For liquid drugs, place one drop onto the plate.

2 Advisedly place ane drop of reagent onto the sample. Do not let the canteen affect the sample or you volition contaminate the entire bottle of reagent. If you are using a ii-bottle reagent such as Simon'due south, Folin, or Morris, place one drop from canteen A and then one drib from bottle B onto the same sample.

3 Find the color change and compare with the enclosed color chart. Nigh reagents volition change color inside xx seconds.

Ehrlich's reagent can take up to 5 minutes.
Morris reagent needs to be stirred (utilize a toothpick or the sharp point of a knife).

The terminal color will appear later stirring for a full xxx seconds.

4 Repeat. Most drugs need to be tested with more than ane reagent. When using multiple reagents, put the cap dorsum on the first reagent and repeat the process with the next reagent using a new sample from the same batch that you're testing.

5 Clean upwardly. Utilize blistering soda to neutralize five the chemicals, then wash the plate with soap and water.

STORAGE AND HANDLING

Go on reagents out of rut and sunlight to prolong the shelf life. If stored in a refrigerator or freezer, most reagents will last a year or longer. (Make sure to thaw them out to room temperature before use.) Dispose of unused reagents at a hazardous waste facility.

Mandelin reagent starts out low-cal orangish in color and turns cloudy yellow later on 3-iv weeks. This is okay. Make sure to shake the bottle before each use.
Marquis and Mecke reagents brainstorm as clear liquids and gradually darken over time. This is okay. They are only expired when the liquid in the bottle becomes so nighttime that you can no longer see the color reaction.

caution If contact is made with the skin, wash with water immediately. If information technology gets in the eyes, overflowing the eyes with water for at least 10 minutes, holding them open. If accidentally ingested, rinse the mouth. Do not induce vomiting. Drink water and seek immediate medical attention.
