Final answer:
Solubility, chemical reactivity, and electric charge are key properties that can be used to separate pollutants from other substances, while mass and volume are less specific to this task.
Step-by-step explanation:
When looking to separate pollutants from other substances, you can leverage various properties of molecules. Solubility (C) is one such property that can be very effective in separation processes. Chemical reactivity (B) is another critical property, as it defines how a substance reacts with others, which can be used to separate it in a controlled reaction. Electric charge (D) is also a significant property since charged particles can be separated by electric fields. While mass and volume (A) are fundamental physical properties, they are less likely to be utilized on their own for separating pollutants without being part of a larger process like distillation (which involves boiling points).
In summary, properties that can be used to effectively sort and separate pollutants from other substances can include chemical reactivity, solubility, and electric charge. Mass and volume are fundamental physical properties but are less specific for the purpose of separating out pollutants.
