PURE water is not a solution. Since it is a pure substance (H2O), it lacks the requirement of another part.
An oatmeal raisin cookie is not a solution since it is not a homogeneous mixture. It is a heterogeneous mixture.
Copper is another example of a pure substance (Cu), although it is used in many alloys, which ARE solutions.
Vinegar is the only one that is a solution. Vinegar is a homogeneous mixture, and can contain a wide variety of acids, the primary being Acetic acid.

Why do vinegar and salt clean iron oxide from pennies?
Vinegar and salt solution, the acetic acid from the vinegar dissolves the copper oxide. The copper from the copper oxide stays in the liquid
How is a brass solution prepared?
Diluted vinegar solution can also be used to clean brass. It can be prepared bymixing one part of vinegar with ten parts of water.
What is created when a penny sits in a paper towel wrapped in vinegar?
Pennies get dull over time because the copper in the pennies slowly reacts with air to form copper oxide. Pure copper metal is bright and shiny, but the oxide is dull and greenish. When you place the pennies in the vinegar solution, the acetic acid from the vinegar dissolves the copper oxide, leaving behind shiny clean pennies.
Why do pennies turn black?
Half-reactionsSince 1982 US cents have been made of zinc plated with a thin layer of copper. It took the Mint several years to stabilize the plating process to prevent reactions when the coins were exposed to air, dirt, skin oils, and such. Many early-date zinc cents exhibit black spotting and mottling because of those problems. Vinegar ReactionIdeas suggests that the acetic acid in vinegar reacts with the copper oxide that has formed on older pennies, and the resulting byproduct is copper acetate. The copper acetate then dissolves in the vinegar solution, therefore getting rid of the black color-producing agents and making it a bit shinier, although it will not appear as shiny as it once was with just vinegar.Vinegar and Salt ReactionThe vinegar in this solution does its job and removes the copper oxide, thus getting rid of the black color. If you place the pennies in the salt and vinegar solution, then take them out without rinsing them, the surface will turn greenish if given ample time to do so. This reaction may become apparent within a few hours or up to a week. Science Project Ideas calls this reaction verdigris; this name can reference many different copper compound reactions, including the one that the salt and vinegar mixture produces. Copper chloride is the name of the chemical reaction of mixing the copper and the sodium chloride from the salt. Copper acetate is the name for the reaction of the copper and acetic acid in vinegar. To prevent this copper reaction, just rinse the pennies after you take them out of the solution
What will happen if copper dipped in a vinegar?
Copper reacts with the oxidilized copper on the penny.
What metal goes green in vinegar?
The metal that will turn green in vinegar is copper. Many people place copper in vinegar as a way to give it a very fast patina.
How do you reverse the oxidation of copper?
ketchup - the vinegar ( acetic acid ) in ketchup changes the copper oxide to copper acetate which is soluable in water.
Is copper fillings a solution?
It is not a solution !
How can you safely clean lime from copper?
Vinegar will do it.
Why garlic in vinegar turns to green?
I turned white vinegar green by putting a 1969 penny in it for two weeks in the refrigerator. It turned green because of the copper in the penny reacting with the vinegar in a process called oxidization. The green was the copper oxide formed when the copper in the penny oxidized in the vinegar.
How do you get copper from copper sulfate solution?
Copper can be obtained from copper sulfate solution by electroplating it onto an electrode or by adding a metal higher in the electromotive series than copper, such as iron, to the solution. The more active metal will dissolve by displacing copper in metallic form from the copper sulfate.
What the three chemicals plays the same role in oxidation as vinegar effects on copper?
no):
