Positive result for bial-orcinol test?
bluish color if pentose is present.
What does bial's orcinol test determine in samples?
The positive result- the resulting blue solution, indicates that the test carbohydrates is a pentose(ribose for example). The blue color is due to the iron content of ferric chloride.
What does bial-orcinol reagent composed of?
300 mg of orcinol in 100 ml of conc. HCl and 0.25 ml of ferric chloride solution (10g / 100ml ).

What does bials orcinol determine in nucleic acid?
Bial's test is used to determine the presence of a pentose sugar. For example, the sugar ribose would turn green (positive) and the sugar glucose would turn brown or yellow (negative). Nucleic acids (DNA and RNA) both contain a suger. RNA contains ribose, so it should have a positive orcinol test. DNA contains deoxyribose, which should have a weak reaction, yielding what appears to be a negative result.
