What is the environmental implication of high solubility?

• A. Chemical more readily evaporates
• B. Chemical binds tightly to soil
• C. Chemical more readily dissolves in water
• D. Chemical decomposes quickly

Answer: (C)

High solubility means a chemical readily dissolves in water, so it tends to stay in the aqueous phase rather than getting attached to soil particles. This makes the substance more mobile in the environment, allowing it to move with groundwater and surface water, spread through runoff, and reach aquatic ecosystems and potentially drinking water supplies. Because it remains dissolved, it can be more challenging to remove with soil-based containment and may require water treatment or remediation that targets dissolved contaminants. Volatility and decomposition rate are separate properties: high solubility does not imply that a compound will evaporate quickly, nor does it say anything about how fast it breaks down.
