What color will be produced by proline with ninhydrin?
When ammonia or primary and secondary amines are detected, a deep blue or purple color known as Ruhemann's purple is produced. Ninhydrin can also be used to monitor deprotection in solid phase peptide synthesis (Kaiser Test). The chain is linked via its C-terminus to the solid support, with the N-terminus extending off it. When that nitrogen is deprotected, a ninhydrin test yields blue. Amino-acid residues are attached with their N-terminus protected, so if the next residue has been successfully coupled onto the chain, the test gives a colorless or yellow result.
What is dry test and wet test of anions?
The dry test of anion is a preliminary test performed to detect the presence of element in compound by introducing the sample to the flame for noting the color produced since certain element can be detected by means of their characteristic flame color. similarly, The wet test of an anion is the test which is based on the principle of treating solution with succession of reagents so that each reagent can separate a group of reagent.
Why should excess cuso4 not be used in biuret test?
the color of the salt prevents the recognition of the color produced in the reaction. The presence of ammonium salts interferes with the test hope usefull :D source: Experimental Organic Chemistry - James F. Norris, Ph.D. in chapter 26
What color flame will rubidium give off?
the color of the flame produced when you burn rubidium is tha same color OS what potassium produce-the colour violet
Why does increasing the amount of substrate increase the amount of color produced in the test tubes?
Not sure of the reaction you are referring to, but in general think of it like adding food coloring into water. The more food coloring you add the more color you get.

What does it mean if no color is produced in a flame test?
The elements contained in this molecule are not able to give a color in the flame.

How does Benedicts test indicate hydrolysis of sucrose and starch?
Benedict 's solution contains Copper , which can accept electrons from reducing sugars and consequently change color. A positive Benedict's sugar test will produce an orange to brick-red color. Reducing sugars have either a free aldehyde functional group or a free ketone functional group as part of their molecular structure; starches and other polysaccharides lack these functional groups . If Benedict's test changes color ( pos. reaction ) polysaccharides must be hydrolyzed.

How do you make the color brown out of food coloring?
Brown may be produced by combining red and green food coloring. It would be wise to make a small test batch to determine the proportion of each color.

Where can one have a color vision test?
One can have a color vision test on the 'Color Vision Testing' website which tests for color blindness. One can also have a similar test at their local opticians.
The ishihara test is a test for what?
