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 reagent bromthymol blue or phenolphthalein could be considered to be an acid indicator?
Bromthymol blue is yeloww in acidic solutions, penolphthalein is colorless.
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 color does blue litmus turn in a base?
Blue.

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.

Bromthymol blue is yeloww in acidic solutions, penolphthalein is colorless.
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 are indicators in acid-base reactions?
Indicators change color based on the pH of the solution. You want to pick an indicator with a similar pKa (acid-dissociation constant) as the pH at which the reaction becomes what you desire it to be. Examples include phenolphthalein, bromthymol blue, and phenol red.

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 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.
Can bromthymol blue be used as a stain for a cheek cell in compound microscopy?
Yes

What color does blue litmus turn in a base?
