What else can I help you with?
What is the color of BTB solution after you exhaled into it?
It turns yellow after we exhaled into the btb solution..:)
What color is BTB in an acid?
BTB stains hands and clothes. As carbon dioxide is absorbed from the breath into the solution, forming carbonic acid, the solution changes color from green to yellow.
What colour does BTB get in an alkaline solution?
In an alkaline solution, bromothymol blue (BTB) turns blue.
What color will appear if you add NaOH to BTB?
Adding NaOH (sodium hydroxide) to BTB (bromothymol blue) will turn the solution blue, as the color of BTB changes depending on the pH of the solution. When NaOH is added, it increases the pH, causing BTB to shift from yellow to blue.
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 color of BTB solution after you exhaled it?
A BTB (bromothymol blue) solution changes color to yellow after carbon dioxide from exhaled air reacts with water, forming carbonic acid. This change indicates the presence of an acidic solution.
What colour does BTB get in an alkaline solution?
In an alkaline solution, bromothymol blue (BTB) turns blue.
What color will appear if you add NaOH to BTB?
Adding NaOH (sodium hydroxide) to BTB (bromothymol blue) will turn the solution blue, as the color of BTB changes depending on the pH of the solution. When NaOH is added, it increases the pH, causing BTB to shift from yellow to blue.
What color is the bromthymol blue solution before and after you exhaled into it?

What color you get after mixing lemon juice to BTB solution?
When you mix lemon juice with bromothymol blue (BTB) solution, the color will change from blue to yellow. This is because the acidity of the lemon juice causes the BTB indicator to shift to its yellow color.
Why does adding carbon dioxide to BTB solution cause a color change?
Adding carbon dioxide to bromothymol blue (BTB) solution causes a color change because it forms carbonic acid, which lowers the pH of the solution. BTB changes color in response to pH changes, shifting from blue in a basic solution to yellow in an acidic solution. The increased acidity due to the carbon dioxide causes the solution to turn yellow.
What color does BTB turn when mixed with a acid or a base?
Bromothymol blue (BTB) turns yellow in the presence of an acid and blue in the presence of a base.
Why does adding air from an air pump cause a color change in btb solution?
When air is pumped into a BTB (Bromothymol blue) solution, carbon dioxide in the air forms carbonic acid when it dissolves in the water, lowering the pH and causing the solution to change color. BTB is an indicator that changes color in response to pH changes, shifting from blue in a basic solution to yellow in an acidic solution.
Which indicator is pale blue in plain water and turns yellow in the presence of an acid?
Bromothymol blue is pale blue in plain water and turns yellow in the presence of an acid. It is commonly used as a pH indicator in science experiments to detect the acidity or basicity of a solution.
What is BTB solution used for?
BTB solution or bromothymol blue solution is an indicator for CO₂ turning a light green or yellow (extreme) depending on the amount of CO₂ indicated. As an student from a school that has recently done this experiment I can verify this information
