What happens if you mix bromphenol blue and NaOH?
When bromophenol blue is mixed with NaOH, the solution turns blue because the pH becomes alkaline. Bromophenol blue is a pH indicator that changes color in different pH ranges. In the presence of NaOH, which is a base, the bromophenol blue changes from yellow (at acidic pH) to blue (at alkaline pH).
Why bromophenol blue is blue color?
Bromophenol blue is blue in color because of its molecular structure, which contains a conjugated system of alternating single and double bonds that allows it to absorb light in the visible spectrum, particularly in the blue region. This absorption of blue light gives the compound its characteristic blue color.
What color is bromophenol blue?
Bromophenol blue is a pH indicator dye that changes color depending on the acidity of the solution. In an acidic environment, it appears yellow, while in a neutral to alkaline environment, it appears blue.
Does Amax of bromophenol blue vary with concentration?
Yes, the absorbance maximum (Amax) of bromophenol blue does vary with concentration. As the concentration of bromophenol blue increases, the Amax shifts from its initial value. This change in Amax can be used to determine the concentration of bromophenol blue in a solution through spectrophotometric analysis.
Which is more polar bromophenol blue or phenolphthalein?
Phenolphthalein is more polar than bromophenol blue due to its structure and functional groups. Phenolphthalein contains more oxygen atoms that can participate in hydrogen bonding, making it a more polar compound compared to bromophenol blue.

What does dye contain?
The loading dye comprises bromophenol blue, Ficoll 400 and water majorly while Xylene cyanol, Tris and EDTA are optional in it. Bromophenol blue is one of the most popular indicators of DNA in agarose gel electrophoresis. Bromophenol blue is a pH indicator.
What is the pka of bromophenol blue?
Phenols are acidic substances (pH over 7).
Can you use bromothymol blue in place of bromophenol blue?
no.heres why:bromophenol-blue-1bromothymol-blue-1
What color is neutral wire in Australia?
The colour of the neutral wire in Australia is blue with marking N.
Can you use bromophenol blue in place of bromothymol blue?
No, bromophenol blue and bromothymol blue are not interchangeable. They have different pH ranges for color changes and may not give accurate results if substituted for each other in experiments or procedures.
If you add a bromophenol blue solution to .01M HCl what solution color would result after mixing?
The bromophenol blue will turn yellow in the presence of an acidic solution like 0.01M HCl.
What colour does pH paper turn in neutral solutions?
in neutral solutions ph paper turns to blue!
