Show hintHide hint
Think about the ratio of concentrations.
Question 2.
What does hydrophobicity indicate?
Show hintHide hint
Consider how a substance interacts with water.
3Question 3.
What does KOC represent?
- The ratio of concentration in organic carbon to water
- The ratio of water to organic carbon
- The valuation of soil quality
Show hintHide hint
Focus on the chemical interactions with organic matter.
4Question 4.

- True
- False
Show hintHide hint
Think about where the chemical accumulates.
Question 5.
Given a set of chemicals with varying KOC and KOW values, predict which chemical would be most likely to accumulate in aquatic life and explain your reasoning.
Show hintHide hint
Evaluate both KOW and KOC values.
Question 6.
Design an experimental setup to measure KOC for a novel chemical. Outline the steps you would take, the controls necessary, and how you would analyze the results.
Show hintHide hint
Consider controls from past studies and the need for standard organic carbon sources.
