Questions: 1. the BTB changes color (from blue to yellow) even though you added nothing to it. If the mixture in the center of the circle produced a gas would this explain the change in the drops of BTB? use the kinetic molecular theory to explain.2. after replacing the center mixture with a mixture of NaOH and NH4Cl the BTB changes back to blue. Explain what happens in terms of the kinetic molecular theory.3. Design an experiment to observe the effect of the size of the BTB drops on the rate at which they change. Describe and list the steps in your procedure. Explain your results in terms of the kinetic molecular theory
