Water Plants In Btb Experiment By Sylvie Dworshak On Prezi The document describes an experiment to investigate photosynthesis and cellular respiration using the ph indicator bromothymol blue. in the photosynthesis portion, elodea plants are placed in bromothymol blue solutions and exposed to light or kept in the dark. Explore cellular respiration with this lab exercise using bromothymol blue. measure co2 levels during rest and exercise.
Experiment 12 B Gotten Life Updates And Whatnot Youtube Carbon dioxide production can be measured by breathing through a straw into a solution of bromthymol blue (btb). btb is an acid indicator; when it reacts with acid it turns from blue to yellow. Always wear eye protection and gloves when doing chemistry experiments rubbing alcohol is flammable, so it must be kept away from any open flames or heat. conduct this experiment in a well ventilated area. procedure: part a: resting (no exercise) measuring carbon dioxide production:. Use acidic and basic solutions to show students how btb changes colors and why it is known as an indicator. you can also show them other indicators, like phenol red and show them how ph paper works. If concentrated bromothymol blue (btb liquid) is available, dilute with water (distilled works best) and test the concentration by adding 10 ml of your btb solution to 15 ml water and bubbling one lung full of air through a straw into the water. it should turn greenish.

Design an experiment to monitor a plant’s photosynthesis and respiration using the colorful ph indicator btb. predict how a plant in the light or in the dark will change the color of the btb solution. Bromothymol blue is an acid base indicator with a pka of 7.2. it is blue in solutions with a ph ≥ 7.6, yellow in ph ≤ 6.0, and greenish in between. a person’s breath contains carbon dioxide which reacts with water to produce carbonic acid according to the following equilibrium reaction: co 2 (g) h 2 o (l) ⇆ h 2 co 3 (aq). Bromothymol blue & aerobic respiration… 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. Students start with a beaker of diluted bromothymol blue (btb), which is a ph indicator. by blowing carbon dioxide into the btb solution, they can change the indicator to green because carbon dioxide mixed with water creates carbonic acid.
