Which statement about solidification of a hazardous liquid is correct?

The correct choice highlights that solidification of a hazardous liquid indeed makes the material easier to handle. When a hazardous liquid is solidified, it typically becomes less mobile, reducing the risks associated with spillage or leaks during transport and storage. This also facilitates safer disposal methods, as solidified materials can often be handled and transported more safely than liquids.

For example, solidified hazardous waste can generally be contained and transported in a way that minimizes exposure risks to individuals and the environment. This improved manageability is a significant reason why solidification is often employed as a treatment method for certain types of hazardous wastes, providing enhanced safety during subsequent handling processes.

While solidification may change the physical state of the material, it does not necessarily alter the underlying chemical properties. The permanence and suitability of the solidified material for long-term storage or disposal can vary and depend on several factors such as the specific type of hazardous waste and the methods used for solidification. Hence, solidification should be viewed as a handling and disposal strategy rather than a definitive permanent solution.
