Italian salad dressing is a suspension, not a solution. If left to stand without shaking, it will easily separate into oil and water components, with the herbs and spices as suspended solids.
Oil and vinegar are a mixture. After a while they will separate.
Salad dressing is a heterogeneous mixture of oil, vinegar, and various other ingredients.
no
If you can see particles (like spices) in it, it's not a solution.If it separates, it's not a solution.Italian dressing has both those properties, so it's not a solution twice over.
Short answer: No. A salad dressing is specifically a colloid emulsion (when shaken/prepared), but easily becomes a suspension as the oil and water (in the vinegar) separate over time. On top of that, things like mustard seeds and herbs cause the dressing to become a mixture (as they could be filtered out). A salad in its entirety is a mixture, as the leaves are not dissolved in the dressing. So, salad cannot be a solution and neither is its dressing.
