Test For Reducing Sugars: A few sugars, for example, glucose are called reducing sugars since they are equipped for exchanging hydrogen electrons to different intensities and the procedure is called reducing.
The color fluctuates from green to dim red block or corroded cocoa, depending upon the measure of and sort of sugar. This test frames a copper thiocyanate which is white and can be utilized as a part of a titration. This was named after American scientist Stanley Benedict.
However, other reducing substances additionally give a positive response. This incorporates all monosaccharides and numerous disaccharides, including lactose and maltose. Along these lines, despite the fact that the ketose fructose is not entirely a reducing sugar, it is an alpha-hydroxy-ketone and gives a positive test since it is changed over to the aldoses glucose and mannose by the base in the reagent.
This test has actually quite a simple principle. The shade of the obtained material gives a thought regarding the amount of sugar present in the compound. The test is semi-quantitative. A greenish color demonstrates around 0.
At the point when reducing sugars are warmed in the essential compound, they shape effective reducing mixtures known as enediol. Thus, we distinguish the presence of reducing compounds. The procedure for this test is one of the easiest ones in the field of biological tests.
With the help of little equipment, you become able to perform the test. Once having all of this things, you can proceed with the following tests. Start heating the solution after it is being added in the test tube gently.
What would be the results? You are going to know this after reading the precautions. Precaution needed to take for Benedicts test: Before performing any scientific test, scientists have enlisted some precaution that is very necessary to be taken.
If you fail to take these particular precautions, there are always chances that you test will be a failed one. Heating the mixture should be a gentle procedure. Just keep it plain and gentle. While adding the solution, just make sure that you adding only a few drops of it. Adding the solution in more quantity could ruin the whole process.
During the heating of the solution, make sure that it is not facing any human. Because on boiling the droplets could escape the test tube and burn the skin of any person who gets in contact.
The last thing is very important. There are possibilities that you may not get results on the first time heating but do get after heating twice or thrice. I am sorry that I had to keep you waiting for results. How will you know that the test you are performing is negative or positive?
Following are the results and observations. If the sugar is reducible: In the case when sugar is reducible, the solution will change its color after the heating process.
It is not necessary that it would happen after heating just once. As mentioned in the precautions, you should try heating twice or more than it and this might bring you results.
If the sugar is non-reducible: After heating the solution once, twice or thrice and the color remains same, then it means that the sugar in the solution is non-reducible. So this was all from a very easy test to check for reducible sugar in the solution.

Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent named after American chemist Stanley Rossiter Benedict.  It is a complex mixture of sodium carbonate, sodium citrate and copper(II) sulfate pentahydrate.
