How do you think bromothymol blue solution works?
Bromthymol Blue, when heated in a solution, indicates carbon dioxide. If there is carbon dioxide in the solution, it will turn bright yellow (when heated).
How one might use bromthymol blue and phenolphthalein to test the ph of water in a swimming pool?
Having just done an experiment in class I think I can answer this. In a test tube collect some swimming pool water then add some bromthymol blue and phenolphthalein and using pH paper dip it in the solution to determine the pH.
What happened to the distilled water in the beaker add 20 drops of bromthymol blue?
When 20 drops of bromthymol blue are added to distilled water in a beaker, the solution will change color depending on the pH level of the water. Bromthymol blue is a pH indicator that turns yellow in acidic conditions (pH below 6) and blue in basic conditions (pH above 7), while it remains green in neutral conditions (around pH 7). Since distilled water is typically neutral, the solution will likely appear green. However, if there are any impurities or if the water's pH is altered, the indicator may show a different color.
Why did the color of the Bromthymol Blue (BTB) solution change in certain test tubes?
if the bromthymol blue changed back to blue from a different color that means that different atoms of another element were in the air. if you tested the bb in a test tube and say it was turned yellow and then overnight it turned back to blue-green then it would mean that a certain amount of oxygen went into the test tube to reverse the change. if there was lots of oxygen in the air then the bb would turn completely blue since bb is not really blue but a weird green color.
Heating causes a bromthymol blue indicator solution to change yellow to blue rapidly why?
AnswerBromthymol blue is an indicator solution that turns yellow in the presence of carbonic acid (H2Co3). Chemically, water and carbon dioxide combine to form carbonic acid. Heating the solution favors the dissociation of carbonic acid back to carbon dioxide and water and therefore the bromthymol blue returns to its less acidic state and back to it original blue color.Answer$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
What color is bromthymol blue when in a base?
Bromthymol blue is blue in a basic solution.
When will Bromthymol blue turn yellow?
Bromthymol blue turns yellow in acidic conditions with a pH below 6.0.
Can reagent bromthymol blue or phenolphthalein could be considered to be an acid indicator?
Phenolphthalein is typically used as a base indicator as it changes color in the presence of bases. Bromthymol blue can be used as both an acid and a base indicator, with different color changes for each.
What color is the bromthymol blue solution before and after you exhaled into it?
The color of the bromthymol blue solution or blue btb is yellow after you exhaled into it..:)
Why did we use bromthymol blue in this experiment?
Bromthymol blue was used in the experiment as an indicator to monitor changes in pH. It changes color in response to pH changes, turning from blue to yellow in an acidic environment and blue to green in a neutral to basic environment. This allows us to visually track any changes in pH during the experiment.
Can bromthymol blue be used as a stain for a cheek cell in compound microscopy?
No, bromthymol blue is typically used as a pH indicator, not a stain for cells. To stain cheek cells for microscopy, dyes like methylene blue or eosin are commonly used as they specifically bind to cellular components and enhance contrast for better visualization.
When mixed with a drop of bromthymol blue what will cause the indicator to turn from blue to yellow?
An acidic solution will cause bromthymol blue to turn from blue to yellow. This color change occurs due to a change in the pH of the solution, with acidic conditions resulting in the indicator changing to a yellow color.
What is the function of bromthymol blue in CO2?
Bromthymol blue is used as an indicator to detect the presence of carbon dioxide (CO2) in a solution. It changes color in the presence of acidic conditions, which can indicate the presence of CO2 as it forms carbonic acid when dissolved in water.
