You can test for acids and alkalis by two different ways:
-Litmus paper reactions
-Universal indicator reactions
Both ways will allow you to see colour changes and this will tell you if it is an acid or an alkali and what PH it is.
Nitroprusside test detects the presence of cysteine and cystine amino acids. These amino acids react with nitroprusside to form a purple color complex, indicating a positive test for cysteine or cystine.
Amino acids that contain an indole group, such as tryptophan, give a positive Ehrlich test. The Ehrlich test is a colorimetric test that detects compounds containing indole or phenolic groups by producing a pink or red color when reacted with p-dimethylaminobenzaldehyde reagent.
No, Ninhydrin is not used to test for the presence of lipids. Ninhydrin is commonly used to detect the presence of amino acids or proteins by producing a purple color when in contact with them. Lipids are usually tested using methods like the Sudan Red test or the paper towel test.
The element that is detected in the lead acetate test for amino acids is sulfur. This test is used to identify the presence of sulfhydryl (thiol) groups in amino acids, which react with lead acetate to form a precipitate.
No, carboxylic acids and alpha-hydroxy ethers do not give a positive Tollen's reagent test. Tollen's reagent is typically used to test for aldehydes and alpha-hydroxy ketones, which undergo oxidation to carboxylic acids in the presence of Tollen's reagent. Carboxylic acids and alpha-hydroxy ethers do not contain the specific functional groups that can undergo this reaction with Tollen's reagent.
