Click to see full answer. Just so, what is koh used for in cellular respiration? Potassium Hydroxide (KOH) is used to alter the equilibrium. Potassium hydroxide removes the carbon dioxide and oxygen is used by cellular respiration thus decreasing the volume of gas in the respirometer.
The purpose of this lab was to determine the rate of cellular respiration in germinating peas by measuring the consumption of oxygen at various temperatures. Herein, what is the role of KOH in this experiment?
Potassium Hydroxide (KOH) is used to alter the equilibrium. Potassium hydroxide removes the carbon dioxide and oxygen is used by cellular respiration thus decreasing the volume of gas in the respirometer. The germinating peas in tube A have used up the most oxygen and have the highest rate of respiration.
The KOH binds with the CO2 and forms a solid at the bottom of the vial, allowing us to accurately measure the oxygen consumption without the release of carbon dioxide interfering. Why did the vial have to be completely sealed around the stopper?

The vial needed to be completely sealed around the stopper because it insured that the measurement of the pressure in the test tube to be accurate. If it hadn't been tightly sealed, the air inside of the test tube would escape, causing the pressure of the oxygen to be impossible to be measured.
