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.

How can I quickly patina copper?
To quickly patina copper, you can use a solution of vinegar and salt or ammonia and salt. Simply apply the solution to the copper surface and let it sit for a few hours or overnight to achieve the desired patina effect.
How can I create etchings on copper using vinegar?
To create etchings on copper using vinegar, you can first clean the copper surface and then apply a protective layer of wax or resist. Next, you can draw your design onto the copper using a sharp tool. Then, immerse the copper in a vinegar solution for a period of time to etch the exposed areas. Finally, remove the resist and clean the copper to reveal your etched design.
Why do vinegar and salt clean iron oxide from pennies?
Vinegar (acetic acid) helps dissolve the iron oxide (rust) on pennies due to its acidic properties. The salt acts as a mild abrasive, aiding in the removal of the rust when rubbed or scrubbed against the penny surface. Together, the vinegar and salt solution create a chemical reaction that breaks down the iron oxide and helps restore the pennies' shine.
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.
How can I quickly turn copper green?
To quickly turn copper green, you can use a mixture of vinegar and salt or a commercial patina solution. Simply apply the solution to the copper surface and allow it to sit for a few hours or overnight to achieve the desired green patina.
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.
How can I give copper a green patina?
To give copper a green patina, you can use a mixture of vinegar and salt to create a solution that can be applied to the copper surface. This solution will react with the copper over time, causing it to develop a greenish color. You can also expose the copper to the elements, such as moisture and air, to naturally develop a patina over time.
How can I achieve a blue patina on copper?
To achieve a blue patina on copper, you can use a combination of vinegar, salt, and ammonia to create a solution that can be applied to the copper surface. This solution will react with the copper over time, creating a blue-green patina. You can also try using a commercial patina solution specifically designed for copper. Make sure to follow safety precautions and instructions carefully when working with chemicals.
How can copper be oxidized using vinegar?
Copper can be oxidized using vinegar through a chemical reaction that occurs when the copper comes into contact with the acetic acid in the vinegar. This reaction causes the copper to lose electrons, resulting in the formation of copper oxide on the surface of the copper.
5kinds of mixtures that is hetomogeous or homegeous?

Why does vinegar and salt clean a penny better than lemon juice?
Vinegar is a weaker acid than lemon juice, allowing it to dissolve the copper oxide layer on the penny more slowly and gently. The addition of salt in the vinegar solution helps to increase conductivity and enhance the cleaning effect by creating an electrolyte solution that speeds up the chemical reaction between the vinegar and the copper oxide on the penny.
What is the best method for creating a copper patina solution for aging metal surfaces?
The best method for creating a copper patina solution for aging metal surfaces is to mix vinegar and salt in a spray bottle and apply it to the metal surface. This solution will help create a natural patina over time.
