What is the color of BTB solution after you exhaled into it?
It turns yellow after we exhaled into the btb solution..:)
What is the function of bromthymol blue in CO2?
It acts as an indicator so it changes color
Why is the vinegar diluted before titration?
1. The advantage in diluting the solution before titration is that it allows for greater accuracy in the titration; this is because the color change in the solution is easier to observe if it is a dilute solution.
What color is Lugol's solution prior to changing color?
Lugol's solution is a solution of iodine (1-5%) and potassium iodide in water. So the solution should have the pale color of iodine and the color should be pale (light) brown.
What is the color of iron (III) chloride solution?
The color of iron (III) chloride solution is brown.

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.
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.
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.
