Why doest fresh water containing bromothymol blue turns yellow?
Hydrogen Chloride (HCl) is an acid. Bromothymol blue turns yellow as HCl is placed in it. Acids change the color of bromothymol blue from green-yellow, depending on whether it is a strong acid or a weak acid.
What is the pH indicator used in the citrate test?
Bromothymol blue is the pH indicator used in the citrate test. It turns blue at an alkaline pH, indicating that citrate has been utilized by the bacteria.
Is bromothymol blue in blue food coloring?
No, bromothymol blue is not typically used in blue food coloring. Blue food coloring usually contains synthetic colorants such as Brilliant Blue FCF (Blue 1) or Indigo Carmine (Blue 2), which are specifically approved for food use by regulatory agencies. Bromothymol blue is more commonly used as a pH indicator in laboratories and not intended for consumption.
Is biuret solution the same as bromothymol blue?
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 does photosynthesis have to do with the use of Bromothymol Blue?
Bromothymol blue is an indicator which changes colour in the presence of an acid. When carbon dioxide mixes with water it produces carbonic acid (soda water). A pretty common experiment involves putting a respiring organism in water mixed with bromothymol blue, the water should turn yellow as the organism takes in oxygen and produces carbon dioxide. The indicator can be changed back to its original blue colour by removing the carbon dioxide from the water, i.e. putting in a plant to run photosynthesis - drawing out the carbon dioxide to produce oxygen.
Why is bromothymol blue used?
Bromothymol blue is used as a pH indicator to detect acidity or alkalinity in a solution. It turns yellow in acidic solutions and blue in alkaline solutions, making it a useful tool for visualizing changes in pH during experiments or in the lab.
Bromothymol blue a base or acid?
yes. bromothymol blue can act as a acid base indicator. becoz in acidic condition(pH:below 7) bromothymol blue is in green colour whereas in alkaline condition(pH: above 7) its colour changes into blue..
Which indicator is pale blue in plain water and turns yellow in the presence of an acid?
Bromothymol blue is pale blue in plain water and turns yellow in the presence of an acid. It is commonly used as a pH indicator in science experiments to detect the acidity or basicity of a solution.
Why doest fresh water containing bromothymol blue turns yellow?
Hydrogen Chloride (HCl) is an acid. Bromothymol blue turns yellow as HCl is placed in it. Acids change the color of bromothymol blue from green-yellow, depending on whether it is a strong acid or a weak acid.
What is bromothymol blue and what is it used for?
Bromothymol blue is used as pH indicator: under pH=6 is yellow and above pH=7,6 is blue. For other applications see the link below.
What is the pH indicator used in the citrate test?
Bromothymol blue is the pH indicator used in the citrate test. It turns blue at an alkaline pH, indicating that citrate has been utilized by the bacteria.

What is a chemical indicator for carbon dioxide?
Bromothymol blue is a chemical indicator that can be used to detect the presence of carbon dioxide. In the presence of carbon dioxide, the indicator changes color from blue to yellow. This change in color indicates the presence of carbon dioxide gas.
Which indicator is used for 8-6 pH?
Bromothymol blue (pH 6.0-7.6) Phenol red (pH 6.4-8.0) Neutral red (pH 6.8-8.0)
What is the BTB?
The BTB stands for: Bromothymol Blue Mostly used for testing the water if there is acid or not.
The scientific method is used to?
Method used to conduct scientific experiments.
How can the scientific method be used?
It can be used to do experiments
