What is the color of BTB solution after you exhaled into it?
If you exhale into a BTB (Bromothymol blue) solution, the ph of the solution decreases due to the presence of carbon dioxide, which causes the solution to turn yellow.
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.
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 colour is biuret before test?
Biuret solution is typically blue-violet in color before the test.
Carbon dioxide is passed into a solution of bromthymol blue indicator until the acid solution turns yellow A sprig of elodea is placed into yellow solution and it turns blue purpose of experiment is?
The purpose of the experiment is to demonstrate the process of photosynthesis. When the elodea plant is added to the yellow solution (indicating acidity), it will consume carbon dioxide and release oxygen through photosynthesis. This will cause a color change in the solution from yellow to blue as the pH increases due to the removal of carbon dioxide.

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.
Heating causes a bromthymol blue indicator solution to change yellow to blue rapidly why?
Heating the solution increases the kinetic energy of the molecules, leading to faster movement and collision. This increased collision rate leads to a faster reaction between the indicator and any substances present that cause the color change from yellow to blue.
Why is the vinegar diluted before titration?
Vinegar is diluted before titration to ensure the concentration of acetic acid in the solution is within the working range of the titration method being used. Dilution also helps in achieving more accurate and precise results by making it easier to measure small volumes of the solution during titration.
What color is Lugol's solution prior to changing color?
Lugol's solution is a brownish-yellow color prior to changing to a dark blue-black color.
What is the color of iron (III) chloride solution?
The color of iron (III) chloride solution is brown.
What color is a neutral solution?
Any color is possible.
What is a color of a solution?
Colorless
