Usually pennies are cleaned by coke. One of the ingredients in Coke is phosphoric acid, a medium strength acid that is used in the production of agricultural fertilizers. It's the phosphoric acid that enables Coke to get stuff off dirty pennies.
Independent variable: This is the one you're changing in the experiment, so it's the type of solution that you're dropping on the penny. Dependent variable: This is the one that you're measuring. In this case, it's how many drops you can get onto a penny without the water spilling off. Control variable: These are things that you keep the same throughout all of the experiments to make sure that your results are actually due to the changes in the independent variable, not some other random change you made. You used the same penny and dropper.
Lemon juice works best for cleaning pennies because the acid helps dissolve the tarnish. Dish soap can also clean pennies by removing dirt and oils, but it may not be as effective at removing tarnish. Water alone may not be sufficient for thorough cleaning.
Yes, dish soap can be effective in cleaning pennies. Soak the pennies in a mixture of dish soap and warm water, then gently scrub them with a soft brush or cloth to remove dirt and grime. Rinse the pennies thoroughly with water and pat them dry to reveal their shine.
