The simplest way is to use litmus papers. Acids turn blue litmus paper red; alkalis turn red litmus paper blue. Other ways include the use of indicators such as universal indicator or methyl orange.
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.
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.
Two ways of identifying amino acids on a chromatogram are by using standards of known amino acid composition to compare retention times and by detecting specific functional groups or side chains using appropriate reagents or detectors.
Strong acids will appear at the lower end of the pH scale, typically around 0 to 3. The color associated with strong acids on pH test strips is typically a bright red to indicate the low pH levels.
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.
To determine the number of ways to complete the test, you can multiply the number of choices for each question. Since there are 3 possible answers for each of the 8 questions, the total number of ways to complete the test is (3^8). Calculating that gives (3^8 = 6,561) ways to complete the test.

take some flashcards that you make for your test and then study 3 at a time make a game show out of your test.and when your done
There are 20-22amino acids. You may be refering to the 4 genetic bases. These are Guanine, Adenine, Thymine and Cytosine.
