No, biuret solution and bromothymol blue are not the same. Biuret solution is a chemical reagent used to detect the presence of proteins, indicated by a color change to purple when proteins are present. In contrast, bromothymol blue is a pH indicator that changes color based on acidity, shifting from yellow in acidic conditions to blue in alkaline conditions. They serve different purposes in laboratory settings.

What chemical reagent of protein?
Biuret reagent is used to test for protein in urine. It is a common test that students in biology class perform. Urine is added to a test tube, followed by approximately the same amount of Biuret reagent. If the solution turns lavender this means that there are proteins present in the urine.
How would you test an unknown solutions for protein?
The biuret test is a chemical test used for detecting the presence of peptide bonds. In the presence of peptides, a copper(II) ion forms violet-colored coordination complexes in an alkaline solution.[1] Several variants on the test have been developed.The Biuret reaction can be used to assay the concentration of proteins because peptide bonds occur with the same frequency per amino acid in the peptide. The intensity of the color, and hence the absorption at 540 nm, is directly proportional to the protein concentration, according to the Beer-Lambert law.
How can biuret test identified peptide bond?
The biuret test is a chemical test used for detecting the presence of peptide bonds. In a positive test, a copper(II) ion is reduced to copper(I), which forms a complex with the nitrogens and carbons of the peptide bonds in an alkaline solution. A violet color indicates the presence of proteins.It is possible to use the Biuret reaction to determine the concentration of proteins because (for most proteins) peptide bonds occur with approximately the same frequency per gram of material. The intensity of the color, and hence the absorption at 540 nm, is directly proportional to the protein concentration, according to the Beer-Lambert law.
When drop of lemon juice are put on blue litmus it turn red what will happen if you put some drops of soap solution on the same position on litmus paper?
The litmus papers are used for checking the acidic and basic nature of any substance. That's why drop of lemon juice, which is by nature acidic, turns blue litmus into red(as the property of acidic solution is to change the color of blue litmus to red). So soap solution which is by nature basic will turn red litmus into blue (as the property of basic solution is to change the color of red litmus to blue).
Are NS and NSS the same solution?
No, NS and NSS are not the same solution. NS refers to Normal Saline, which is a solution of 0.9% sodium chloride in water. NSS refers to Normal Saline Solution, which is the same as NS. Both terms are commonly used interchangeably to refer to the same solution.
Will Yellow Bromothymol Blue revert to Green or Blue color after 12 hours?
No. Bromothymol Blue turns yellow in an acidic solution. If it is in the same solution without any additions, it will stay blue after 12 hours or longer. If the solution is altered by adding base, then the Bromothymol Blue will turn blue or green depending on how much base is added to solution.
Is thymol blue and brothymol blue the same?
Yes, thymol blue and bromothymol blue are two different pH indicators. Thymol blue has a pH range of 8.0-9.6 and changes color from yellow to blue, while bromothymol blue has a pH range of 6.0-7.6 and changes color from yellow to blue.
Colour of sodium hydroxide in bromothymol blue?
Bromothymol blue is a chemical indicator for weak acids and bases. The chemical is also used for observing photosynthetic activities or respiratory indicators (turns green then yellow as CO2 is added). Since dissolved O2 does not affect pH, the solution remains the same color it was when it was added (yellow for acidic, green for neutral, blue for alkaline).
What is a limitation of Bromothymol Blue?
Bromothymol Blue is a liquid indicator that can detect presence CO2 in water. It changes color from blue to green, as it detects the presence of the CO2 . In very acidic conditions it will turn yellow. It has also been used as an indicator in the NCO (isocyanate) test (where di-n-butylamine is the base and 1N HCl solution is the acid. Green is the endpoint in this titration and yellow is "over-shot". The amine value test in resin chemistry/synthesis also may use this indicator. HCl directly titrates an amine containing resin.
What chemical reagent of protein?

Which 2 indicators turn the same colour with hydrochloric acid?
Methyl orange and methyl red both shows red color in a HCl solution where pH is lesser than 4.71.

How You are given three clear colorless unknown solutions and red and blue litmus papers. Describe the steps you might take to correctly identify each solution as acidic basic or neutral.?
Test each unknown solution with both red and blue litmus papers. If red litmus turns blue, the solution is basic. If blue litmus turns red, the solution is acidic. If both red and blue litmus papers remain the same, the solution is neutral.
What is the substances in a living cell that has same function as methylene blue?
NADH
What are the two boils on my goldfish's scales?
That usually means your goldfish will be floating belly up in a few days. Once you see lesions, the ich (see link) has all but taken over the fish's body. You might want to treat the water with bromothymol blue (pet store will have it) if you have other fish in the same tank.
Is a solution the same as a solution?
It seems there might be a typo in your question. If you are asking whether a "solution" is the same as a "solution," then yes, they are the same word. A solution refers to a means of solving a problem or dealing with a difficult situation.
Will the same amount of solution appear to be the same or different when placed in different types of glassware?
If you start out with a solution and you put the same amount of solution in different types of glassware, it will always be the same no matter what.
