You can clean copper pennies that have turned green by using a mixture of vinegar and salt or by using lemon juice and salt. Simply soak the pennies in the solution for a few hours, then gently scrub them with a soft-bristled brush or cloth to remove the green tarnish. Rinse the pennies with water and dry them thoroughly.
One way to separate paperclips from a mixture of salt and pennies is to use a magnet. The paperclips will be attracted to the magnet and can be easily picked up, while the salt and pennies will remain unaffected. Alternatively, you could dissolve the mixture in water, as the paperclips will sink, while the salt will dissolve and the pennies will remain at the bottom.

Green salt is made of a combination of salt, herbs (such as basil, parsley, tarragon, and chervil), and sometimes other ingredients like garlic or lemon zest. The color comes from the addition of these green herbs to the salt mixture.
No, a mixture of vinegar and salt cannot be separated by mechanical separation. Mechanical separation involves physically separating components based on their physical properties such as size, shape, or density. Since both vinegar and salt are soluble in water, they form a homogeneous mixture that cannot be separated by mechanical means. To separate vinegar and salt, you would need to use a different method such as distillation to evaporate the vinegar and leave the salt behind.

Yes, salt can be used to clean pennies. When salt is combined with vinegar or lemon juice, it can create a chemical reaction that helps to remove the tarnish and dirt from the pennies, making them appear cleaner and brighter. Rubbing the salt mixture onto the pennies with a cloth can help to improve their appearance.

You can also turn pennies and some other coins green by letting them sit overnight in a paper towel soaked in vinegar. and if you want to clan pennies to shine, put them in a cup of vinegar and salt dissolved. (I once tried cleaning them with a pinch of kosher salt instead and it dug a hole through the penny! -NOT RECOMENDED!!!)
A mixture of vinegar and salt can effectively clean copper pennies. The acid in vinegar helps to dissolve the tarnish on the pennies, while the salt acts as a mild abrasive to help scrub away dirt and grime. Dip the pennies in the vinegar and salt solution, then rinse with water and dry thoroughly.
