Why does vinegar clean pennies?
The acid in vinegar dissolves the corrosion that builds up on pennies, which is why vinegar is a popular cleaning agent for pennies. The vinegar also breaks down any dirt or grime that may be on the penny.
Why does vinegar clean pennies?
Acetic acid from vinegar dissolves corrosion from copper pennies resulting from oxidation from exposure or exposure under extreme conditions (like storage at extreme temperatures). When these chemicals combine with metals such as copper they form salts called copper salts which are corrosive because they make metals brittle (like rust). Acetic acid breaks down these copper salts because acetic acid does not contain any metals so it doesn’t corrode metal (but rather break down corrosion by removing its main component).
In addition acetic acid reacts with carbon dioxide molecules released during baking soda’s reaction which makes this cleaning mixture even stronger than just using baking soda alone as vinegar removes these CO2 molecules released during baking soda’s reaction too!
This reaction between acetic acid from vinegar dissolves copper salts (which makes pennies corroded) so that they don’t form into more corrosion on copper pennies while cleaning them!
What happens when you soak a penny in vinegar?
Acetate ions from vi reacts with CO2 to produce acetic acid!
If you have a penny in water that has vinegar then it breaks the rust on the metal and removes what’s been corroded which is a reaction between the acetic acid (releasing acetate ions) and these metal salts. This reaction is called hydrolysis and can be described by this equation: $$\ce{H2O(aq)+H3C-COO- <=> HO-COO^-(aq)+H3C=COOH}$$
$$\ce{HO-COO^-(aq) + 2 e^{ – } + 2 H3C = \rightarrow C4O7^{ – } + 3 H_2 O}$$
If we were to calculate the enthalpy change for this reaction then it would read about -26.75 kcal/mol making our reaction exothermic.

How long does it take a penny to turn green in vinegar?
If you put a penny in a jar of vinegar and left it alone, it would likely turn green. The penny is covered in a layer of mold, which is a type of fungus. Mold feeds on sugar and other organic material, and when it grows on a penny, it turns the coin green.
What happens when you put vinegar on a penny?
It creates a reaction that causes the penny to turn into copper chloride
In terms of weight, vinegar is 4.2 times lighter than water and the copper salts are 1.8 times heavier than this liquid
Because of these factors, your penny will fall down due to gravity and when it hits water on a level surface it starts losing mass through evaporation.
Why would a penny turn black?
If it was black, who would it be by?
And if it was black, how would it be taken?
What if a penny turned black and sank into the ground before anyone could follow its lead?
This thought fascinated me.
How much did you have to take to pass from the category of survival toward the category of non-survival?
The basic units in this section of a guide to Fuzzy Logic are some alternatives in any of three dimensions: direction, size, and type.
Now you are going to analyze alternative sets of elements in terms of some ability called their “type.” To clarify what this means, here is a quick definition of type.
How do you clean pennies fast?
Cleaning pennies can be a time-consuming task, but it can be done quickly and easily with a few simple steps. First, use a toothbrush to scrub the pennies clean. Next, fill a small bowl with warm water and soap.
Dip each penny in the water and soap mixture, then scrub it clean with the toothbrush. Finally, rinse the pennies in clean water.

How long do you soak pennies in vinegar to clean them?
The pennies can be soaked in vinegar for at least 2-3 days. However, the coins can be cleaned easily in only 1 day.
Why do pennies turn black in vinegar?
Pennies are made from zinc which turns black when exposed with vinegar solution because zinc reacts with acetic acid (vinegar). This reaction produces carbon dioxide gas which expands into tiny bubbles that form on surfaces where they are trapped by surface tension forces called capillarity effects; these bubble formations are called effervescence or frothiness (or foam).
Conclusion
In conclusion, vinegar works wonders when it comes to cleaning pennies!
It’s because vinegar has an acidic pH level that helps dissolve all sorts of stains on pennies – including those that have been around for years!
Plus, it’s non-toxic and won’t damage your pennies in any way at all!
That means you can clean them without worrying about damaging them or causing them any harm at all!
So next time you have some pennies lying around your house that you want to clean up – don’t hesitate!
Grab some vinegar and get started!
You’ll be amazed at how well it works!
