BTB changes color because of the CO2 in chemicals. When we blow into the BTB with a straw, the water vapor fuses with the BTB and change color. Our breath has some acidic characteristics. The BTB changes from blue, its original color to green-yellow, that's proof that what we breath has acidic molecules.

Color change when bromine water is added to cyclopentane hydrocarbon?
When bromine water is added to cyclopentane, there is no color change observed. This is because cyclopentane is a saturated hydrocarbon, lacking double or triple bonds that would allow for a reaction with bromine. The bromine water retains its reddish-brown color, indicating that no bromination has occurred. In contrast, unsaturated hydrocarbons would react, resulting in a decolorization of the bromine water.
What color would you expect bromothymol blue to be when pure water added?
Bromothymol blue is a pH indicator that appears yellow in acidic solutions and blue in basic solutions. When added to pure water, which has a neutral pH of around 7, bromothymol blue would typically appear green, as it transitions between yellow and blue around this pH level. The exact shade may vary slightly depending on the concentration of the indicator and the specific conditions of the water.
What does food coloring do when it is added to water?
the food coloring slowly moves around in the glass (like smoke would) and that is happening because the particles in the food coloring are not use to the temperature of the water,but as the particles get use to the temperature they move a little faster and spread everywhere in the water. Slowly disperse throughout the water, this is because of diffusion.
What colour would lime water turn in phenolphthaleln?
Lime water, which is a solution of calcium hydroxide, does not change color when phenolphthalein is added. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions. Since lime water is basic, it would typically show a pink color when phenolphthalein is present. However, if the lime water is sufficiently dilute, the color change may not be very pronounced.
What color would phenoplhthalein turn if drano was added?
Phenolphthalein would turn pink when added to Drano, which is a strong alkaline substance. This color change indicates that the solution has become basic.
Explain why you would or would not expect to observe a color change if FeCl3 were added to the following?
you would expect a color change in oil of wintergreen because it has an OH group added to the FeCl3 which causes a purple color
What would you would expect to see if a small piece of sodium was added to cold water?
A violent reaction occur and hydrogen is released.

What colour would water be if you add litmus and acid to it?
Lithmus will give a red color when added to acidified water or it will turn to red when neutral water is acidified.Remember:Litmus turnsBlue in BasicreD in aciD
