Is salad a suspension or solution?

Salad is a suspension. Here's why:

* Suspension: A mixture where particles of one substance are dispersed throughout another, but the particles are not dissolved. These particles are typically visible and will settle over time.

* Solution: A homogeneous mixture where one substance (solute) is dissolved completely into another (solvent). The particles are evenly distributed and don't settle.

In a salad:

* The ingredients (lettuce, vegetables, etc.) are not dissolved in a liquid. They remain as separate, visible particles.

* If you leave a salad sitting for a while, the heavier ingredients will likely sink to the bottom, demonstrating the settling of particles.

Therefore, salad is a heterogeneous mixture classified as a suspension.
