What effect does an increase in Jydrogen ion concentration have on blood pH? 3 70 9.0 90 100 110 120 1. Put 100 ml of distilled water into a 200-ml beaker. 2. Add 10 ml of 0 2M NaOH to the beaker and swirl the beaker gently to mix. 3. Add four drops of phenolphthalein to the solution and swirl the beaker gently to mix. Phenolphthalein is a pH indicator that is colorless in acidic solutions and pinkish-red in basic solutions What color is the solution Figure 3-9 Interpreting pH test strip results. 4. Noting the time at which you do so, use a plastic straw to blow bubbles of exhaled air into the solution Record the time it takes for the solution to change color What does this color change indicate? 4. CHART Record your results in the following chart. 5. Repeat steps 2-4 for each solution Solution PH Acidic, Neutral, or Basic 1. Distilled water 2. Tap water 3. Black coffee 4. Lemon juice 5. Household bleach 5. Have the same student who performed step 4 run in place for 5 minutes 6. While this student is running, prepare another beaker by following the directions in steps 1 and 2 7. Immediately after the student has run in place for 5 minutes, note the time and have the student exhale through a straw into the solution Record the time it takes for the solution to change color 8. Answer the following questions based on your results, 2. What is the effect of exercise on blood Co,levels? 6. Egg white B. Applying the Principles When oxygen is present, the cells of your body break down the simple sugar glucose (CH20. to store energy in a molecule called ATP Carbon dioxide (CO) and water are produced as byproducts of this reaction, which is summarized as follows: CH,06 + 60, 600, + 6H2O + ATP As carbon dioxide enters the blood, it combines with water to form carbonic acid (H.CO), which then dissociates into hydrogen ions (H) and bicarbonate ions (HCO, CÓ, + HẠO- HẠCO, H + HCO, Therefore, an increase in blood carbon dioxide levels results in an increase in blood hydrogen ion levels b. How were you able to draw this conclusion?
