Answer:
the amount of light
the purity of the liquid
the concentration
Explanation:
There are three parameters that affect the absorbance of light. These are the the amount of light, the purity of the liquid and the concentration of the substance. The intensity of the light plays a role in the penetration of the light. A strong wave length light penetrates more. The purity also affects the absorbance. In addition, the concentration of the substance. A more concentrated substance absorbs light more. The focus of the experiment will be on the effect of the concentration of the substance.
