What is a slurry?

1. A solid material that cannot dissolve

2. A pourable mixture of a solid and a liquid

3. A gas mixed with a liquid

4. A saturated solution

The correct answer is: A pourable mixture of a solid and a liquid

A slurry is defined as a pourable mixture composed of solid particles suspended in a liquid. This property allows slurries to be easily transported and handled in various industrial processes. The solid component is typically finely divided, enabling it to remain suspended within the liquid, which can be water or another suitable solvent. The nature of a slurry is critical for many applications, particularly in environmental remediation or in the treatment of hazardous materials, as it allows for easier manipulation and dispersion of solid contaminants in a manageable form. In contrast, the other options do not accurately capture the essence of what a slurry is. A solid material that cannot dissolve does not describe the combination of solid and liquid components found in a slurry, while a gas mixed with a liquid refers to a different type of mixture, often seen in foams or aerosols. Lastly, a saturated solution pertains to a liquid containing the maximum amount of solute that it can dissolve at a given temperature, which is distinct from a slurry where solid particles do not dissolve but remain suspended.
