It is 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.
