The student should wear appropriate personal protective equipment such as safety goggles and gloves, use a clamping device to securely hold the test tube, and heat the test tube gently and evenly by moving the flame back and forth beneath it to prevent boiling over or splattering. It's also important to ensure proper ventilation to avoid inhaling any fumes that may be produced.

What test is specific for pentose?

The specific test for pentoses is the Bial's test. This test involves heating the sugar with orcinol and an acidic solution, resulting in a blue-green color if pentoses are present.


What is the borax test of anthraquinons?

The borax test for anthraquinones involves mixing a sample with borax and heating it to produce a colored solution. The presence of anthraquinones is indicated by the color change in the solution. This test is commonly used to detect the presence of anthraquinones in organic compounds.


Does benedict's solution need heating when testing for glucose?

Yes, Benedict's solution needs heating to test for glucose. Heating helps to facilitate the reaction between glucose and the copper ions in the Benedict's solution, resulting in a color change that indicates the presence of glucose.


When heating liquid in a test tube what safety precautions are needed?

Before heating it, you should check the test tube for damage (scratches or cracks), and not use one that isn't perfect. You should also wear safety glasses (to protect your eyes in case the test tube explodes, which happens sometimes, even when heating water). If you are heating something that could react violently, you should use a blast shield (thick piece of clear plastic).


What biomolecule turns Benedict's solution purple?

Reducing sugars, such as glucose and fructose, can turn Benedict's solution purple upon heating. Benedict's solution is a chemical reagent used to test for the presence of reducing sugars in a given sample.


When heating a test tube one should always use this piece of safety equipment?

When heating a test tube, one should always use a test tube holder. This provides a secure grip on the hot test tube and prevents accidental burns or spills. It is essential for handling hot glassware safely in the laboratory.


When heating a liquid sample in a test tube the mouth of the test tube should be?

It depends on what you are doing, you should be sure to follow instructions carefully and be sure to take proper safety precautions


Why seliwanoff's test gives a color upon long heating a solution of glucose?

Seliwanoff's test is specific for detecting ketoses, such as fructose. Upon long heating, fructose in the presence of concentrated acid will dehydrate to form furfural derivatives, giving a red color. Glucose, a aldose sugar, does not undergo this reaction and will not give a color with Seliwanoff's test.
