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.
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).
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 might cause bromthymol blue to turn murky green?
If the solution is neutral, then it would turn green. B. blue turns yellow in the presence of acidic solutions and blue in the presence of basic solutions.
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.
Can reagent bromthymol blue or phenolphthalein could be considered to be an acid indicator?
Bromthymol blue is yeloww in acidic solutions, penolphthalein is colorless.
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..:)
What is the function of bromthymol blue in CO2?
It acts as an indicator so it changes color
Can bromthymol blue be used as a stain for a cheek cell in compound microscopy?
Yes

When mixed with a drop of bromthymol blue what will cause the indicator to turn from blue to yellow?
Bromthymol Blue indicates Carbon dioxide is present. It is also a general acid-base indicator. When it turns green it is at the endpoint of the titration. When it turns yellow, it is overshot and thus acidic.

What happens when bromthymol blue is exposed to CO2?
According to our experiment, CO2 was released to the BTB, it became like color yellow-green.

What is the advantage of using pHydrion paper rather than bromthymol blue or phenolpthalein?
pHydrion paper gives you an actual pH level rather than if it's an acid or base.
