the Station 1、 Label S vials with the ingSem,10cm, 30cm, Dfo. Dark and N fur no plan. Add 4 ml of the indicarer solution to each vial weing a piperse. Make sore you add esacly 4 l. Hint concentration of CO, in solution) ュRead the Station Nono or ebeck with your TA for Ehe appropriate mount of each vial and place them in 4 arparase vials, NOT the e ial Cap each vial tighely to prevenegs eschange with the air outside the vials 4 Determine initial pH for each vial by holding it ness to the color guide; record inicial pit in the cha 5. Position the vials ar the required distance from the light source S below 10, and 30 em. Completely cover the dark vial using the aluminum foil provided. Make sure no light can get in. Place both thedarke vial and the no plane vial at S em from the light souree. 6. Turn on your light source and set the timer for 20 minutes Results After 20 minntes Is the color change uniform throughout each vial? Match the vial solution color to the color guide and record the pH. Return ehe vials to their respective positions. Set the timer for Is there a color difference between the plant vials and the no-plant vials? Mix the vials by inverting chem gently. Record the pH of each vial by placing the vial next to the pH color vials to their respective positions after you have determined their pH. Set the timer for another 20 minutes Affer 40 minutes the vials by inverting them gently. Record the pHi of each vial by placing the vial next to the pH color guide. INITIAL PH PH AT 20 MINS PH AT 40 MINS VIAL TYPE S. 6 Light at 5 em Light at 10 cm Light at 30 cm 3.2 8.3 1.2 7.27 7.6 7,0 Dark 710 No Plant
