Photosynthesis Investigation Prediction The equation for photosynthesis is: Water + Carbon Dioxide Glucose + Oxygen 6H2O (l) 6CO2 (g) C6H12O6 (aq) 6O2 From this equation it is seen that sunlight is very important in the production of glucose. If all other products are available e.g. water and carbon dioxide in sufficient quantities then light can be used as a variable. If not enough of any reactant is present it will be a limiting factor. This means that no matter how much light is added no more glucose can be made. In our experiment the plant i.e. elodea is placed in water and sodium hydrogen carbonate is added thereby preventing a limiting factor. This is because the water of course is plentiful and the sodium hydrogen carbonate provides the elodea with carbon dioxide. The only way that a limiting factor can be reached is if the temperature rises too high. To prevent this we placed...
