Actually my teacher explained that we require potassium pillets for testing CO2 is required for photosynthetic process and the experiment explained by your website is telling that we need potassium hydroxide which one is correct and which one is wrong?

Expert Answer:

Potassium pellets contain potasium chloride. Potassium chloride cannot absorb carbon dioxide gas.
Potassium hydroxide is used to absorb carbon dioxide gas. This creates a vaccum like conditions and eliminates carbon dioxide completely, which might otherwise interfere in the photosynthesis experiment.
