Is salad dressing a solution or a suspension?
its a suspension. more specifially a colloid. emulsion.
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…
Is salt water aluminum muddy water water tea iron sugar jello gold table salt and Italian salad dressing a pure substance suspension colloid or solution?
Salt water and table salt +water are the same thing- a solution. Aluminum, gold and iron are all elements (pure substances) and can not be broken down. Jello is a colloid. Muddy water is a suspension, plus salad dressing. Perhaps sugar could be called a pure substance. But it can be broken down into its' component parts. Tea also.
