Which statement about polar solvents is true?

The statement that polar solvents do not mix with water is incorrect, as polar solvents are characterized by their ability to mix with water effectively. Polar solvents, like alcohols and acetones, have molecules with partial positive and negative charges, which allows them to interact favorably with water molecules that also have a polar nature. This property is crucial in many applications, including firefighting and chemical handling, as it influences how these substances behave in mixtures and reactions.

In contrast, non-polar solvents do not mix well with water, highlighting the importance of polarity in understanding solvent characteristics. Non-combustibility is not a hallmark of polar solvents either, as many polar solvents can be flammable under certain conditions. Additionally, the hazard level of solvents is not strictly determined by their polarity; some polar solvents can be quite hazardous while certain non-polar solvents may be less so. Understanding these characteristics ensures safer handling and effective usage in various applications, including firefighting.
