Lab Manual 5 1 Level 1 Dissolved Oxygen Do Biochemical Oxygen Unit 2 lesson 6 you will use a ph indicator called btb (bromthymol blue) solution. in this video, you will learn how btb changes its color. not all the materials used in this video are. Write out the formula for cellular respiration (check with partner, then table, then notes). investigate how exercise could affect cellular respiration rate. these are your supplies: 250 ml erlenmeyer flask to hold btb solution straw with cut out hole to exhale into the btb solution.
Dissolved Oxygen Lab By Maurice Montemayor On Prezi Bromothymol blue (also known as bromothymol sulfone phthalein and btb) is a ph indicator. it is mostly used in applications that require measuring substances that would have a relatively neutral ph (near 7). Btb will work the same way when it is more diluted, but the color will appear lighter. if the color is too light when you have btb in shallow petri dishes, then you can use more concentrated btb. A solution of bromothymol blue (btb). btb is an acid indicator; when it reacts w th acid it turns from blue to yellow. when carbon dioxide reacts with water, a weak acid (carbonic acid) is. Learn the essential techniques for creating a standard, reliable bromothymol blue indicator. covers dissolution, safety, and proper storage.

Introduction: this experiment explored how aerobic respiration from exercise affects a basic solution and its transition to an acid. more energy is used during exercise, more oxygen is required in the human body to fuel cellular respiration. Lab protocol to measure the effect of exercise on co2 production using btb. includes procedures, data collection, and expected results. After several breaths, the solution turns more and more yellow as the ph of the solution reaches 6.0. the color change is striking, and students will enjoy watching the instructor puff away into the solution. Btb will work the same way when it is more diluted, but the color will appear lighter. if the color is too light when you have btb in shallow petri dishes, then you can use more concentrated btb.
