Marquis Reagent The Simplest Spot-Test You’ll Get

Thursday 08 November 2018 at 09:36 am.

The marquis test is a really simple type of spot test that you can possibly get when you want presumptive identification of alkaloids and other type of compounds. It is composed mainly of formaldehyde as well as sulfuric acid and it is usually dripped into the substance that you are testing out. It is very simple to use and it is the reason why it is quite popular as well. If you want to try it out but it is your first time using it, here are some of the steps into which you should be able to make things work out. Learn about Marquis Reagent on wimscilabs.com.

Step 1

The first step you need to do would be to scrape off a very small amount of the compound or substance that you want to test. This is easier since you would not be needing to do so much and you also get to somehow find a way to somehow save some of your sample in case you have limited amount of it or if you are planning to subject it for later.

Step 2

The second step involves the use of the Marquis reagent itself in which you are supposed to drop the reagent which is initially colorless and clear in appearance. And then, that is all of it for the step 2 and then you should proceed to step 3 with ease.

Step 3

The last step, the third step is done by analyzing the results of step 2. You should carefully look at the resulting color of the mixture. You should also note the time it took the solution to change in color because this will be very important in identifying your compound. After noting everything, you can compare it out with the test analysis card that your kit should contain so check it there.
