Proteins get denatured when acid is added and this forms a white coagulum which is slightly yellow in colour because of nitro- derivatives of proteins given by aromatic amino acids.

What is the chemical basis for a positive test in Molisch's test?
See this link.
What are the reagent use to identify the cellulose in an experiment?
No test.. You can order standard from Sigma and compare ur sample with FT-IR... Thats all.

How do you test colourless solution?
The substance may glow under UV light or it may be possible to stain it at the end of the process.
Biochemical tests to confirm micrococcus luteus?
I had a bacterial unknown of M. luteus in my microbiology lab. M. luteus is a Gram positive cocci (as seen by a gram stain). A good definitive test for Gram + cocci is the catalase test. M. luteus is catalase positive. Then a nitrate test can be performed to determine that M. luteus is nitrate negative. Those alone should be enough to confirm M. luteus.
What is Perls test?
a test for hemosiderin, utilizing Perls Prussian blue stain.
Why is brown stain not a test for bismuth ion?
it is dark
What test may be used to determine if a stain is blood or not?
Kastle-Meyer Color Test
What is Congo Red?
Congo red is the sodium salt of benzidinediazo-bis-1-naphtylamine-4-sulfonic acid (formula: C32H22N6Na2O6S2). It is a secondary diazo dye. Congo red is water soluble, yielding a red colloidal solution; its solubility is better in organic solvents such as ethanol.It has a strong, though apparently non-covalent affinity to cellulose fibres. However, the use of Congo red in the cellulose industries (cotton textile, wood pulp & paper) has long been abandoned, mainly because of its toxicity.Conga Red is an acidic stain primarily used to stain bacterial cells to test for capsules. The Conga Red stain is used to stain a microscope slide background against the colorless cell. Then a basic stain like Maneval's Stain is used to stain the cell. The capsule surrounding some cells will repel the stains and appear colorless against a red (Conga Red) background. The cell inside the capsule will be stained light purple from the Maneval's Stain.
What is secondary stain?
A secondary stain is Methylene blue. This type of stain is used in a acid fast staining. This type of staining test can determine medical conditions such as tuberculosis.

Why doesn't cellulose give a positive iodine test?
cellulose is derived from D-glucose units, which condensed through beta(1->4)-glycosidic bond. This give cellulose to be a straight polymer therefore, it can't coil around iodine to produce blue color as starch does.
What are the reagent use to identify the cellulose in an experiment?
No test.. You can order standard from Sigma and compare ur sample with FT-IR... Thats all.
What was the purpose of performing the Chi-Square test?
It is often a "goodness of fit" test. This is a test of how well the observations match the frequencies that would have been expected on theoretical basis. The theoretical basis may simply be your hypothesis.
