Is tartaric acid gives tollen's test positive?

yes... it gives silver particle deposition at the bottom of test tube


Why tartaric acid not give phenolphthalein test?

Tartaric acid is a weak acid and does not ionize completely in water to release hydrogen ions. As a result, it does not provide enough free hydrogen ions to turn phenolphthalein indicator pink, which typically requires a pH above 8.2. Tartaric acid's ionization behavior limits its ability to produce the color change associated with the phenolphthalein test.


What is a test for presence of coch3 group?

One common test for the presence of a -COCH3 group is the 2,4-dinitrophenylhydrazine (Brady's) test. In this test, the compound is treated with 2,4-dinitrophenylhydrazine in the presence of acid to form a yellow to orange precipitate, indicating the presence of a ketone or aldehyde functional group.


Which gas will be evolved if Sodium bicarbonate is added to a solution of Tartaric acid. How will you test this gas?

You should get carbon dioxide (CO2). Combining sodium bicarbonate to tartaric acid will yield water-soluble sodium tartrate and carbonic acid. Carbonic acid (H2CO3) will instantly decompose into water and carbon dioxide. Collect the gas, pour it over a lit candle flame. The flame will go out, proving that it's CO2. sodium bicarbonate and Tartaric acid together in dry form are baking powder.


What does the acid test prove when testing minerals?

The acid test is used to determine the presence of carbonate minerals in a sample. If the mineral fizzes or reacts with acid, it indicates the presence of carbonate minerals such as calcite or dolomite.


In lead acetate test what element in the amino acid is detected to be present in this test?

The lead acetate test is used to detect the presence of the sulfhydryl (thiol) group in amino acids, particularly cysteine. When lead acetate solution is added to a sample containing a sulfhydryl group, a black precipitate of lead sulfide forms, indicating a positive test for the presence of sulfhydryl groups.


What is a simple test for presence of tannic acid?

Tannic acid is a type of polyphenol with the chemical formula of C76H52O46. A simple test for tannic acid is to add the substance to distilled water. Then add two drops of ferric chloride. If this results in a greenish precipitate, it indicates the presence of tannic acid.


What is the equation for the reaction of modified furter-meyer test?

The reaction for the modified Fehling's test involves the oxidation of an aldehyde to a carboxylic acid in the presence of copper(II) ions. This reaction results in the formation of a brick-red precipitate of copper(I) oxide, which indicates a positive test for the presence of an aldehyde group.


Does formic acid fehling's test?

No, formic acid does not react in the Fehling's test. The Fehling's test is specifically used to test for the presence of reducing sugars. Formic acid is a carboxylic acid and does not possess a reducing sugar functionality.


What color test tube would I use for a Lactic acid test?

You can use a clear test tube for a lactic acid test. This allows you to easily observe any color changes that may occur during the test, indicating the presence of lactic acid.


Does hcooh undergo fehlings reaction?

No, formic acid (HCOOH) does not undergo the Fehling's test because it does not contain an aldehyde or ketone group necessary for the reaction to occur. The Fehling's test is specifically used to detect the presence of reducing sugars that possess an aldehyde or ketone functional group.


What is the difference between Benedict's solution and fehling's solution?

Benedict's solution is used to test for the presence of reducing sugars, such as glucose, in a sample. It is more sensitive than Fehling's solution, which is also used to test for reducing sugars but is less commonly used due to its complexity and need for separate solutions (Fehling's A and B) to be mixed in a specific ratio before testing. Benedict's solution is a single solution that is easier to use.
