What happens when you mix vinegar with salt?
The combination of salt and vinegar creates sodium acetate and hydrogen chloride. This chemical reaction will take an old penny and shine it like new.
What science experiments can I do with vinegar?
5 Non-Volcano Kids’ Science Activities Using Vinegar
- Ice Tray Battery.
- Chemistry Rocket.
- CO2 Sandwich.
- Folding Egg.
- Flame Light Relight. If you weren’t aware of just what makes the old science fair volcano “erupt,” it’s the production of carbon dioxide gas from the combination of baking soda and vinegar.

What does salt and vinegar do to a penny?
The combination of vinegar (a weak solution of acetic acid), and table salt (sodium chloride) helps to dissolve the copper oxide, and also forms the blue copper(II) ion, which is soluble in water. The penny becomes shiny again!
What substance reacts with vinegar?
The reaction is: Sodium bicarbonate and acetic acid reacts to carbon dioxide, water and sodium acetate. The solid baking soda was placed in liquid vinegar producing carbon dioxide gas, which is evident because of the formation of bubbles in the foaming mixture.
How do Pennies get so dirty?
The negatively charged oxygen atoms in our air are attracted to the positively charged copper atoms in the penny. When oxygen binds with copper, they form a new molecule known as copper oxide. This is why most pennies you see look dirty or tarnished—it’s not actually dirt but copper oxide that makes them look so dull.
What happens when you put zinc in vinegar?
Explanation: Zinc metal will indeed react with vinegar, which is a dilute solution of acetic acid , CH3COOH , to form zinc acetate, (CH3COO)2Zn and hydrogen gas, H2 . Zinc will be oxidized to zinc cations, Zn2+ . At the same time, hydrogen will be reduced to hydrogen gas, H2 .
Does salt and vinegar create hydrochloric acid?
When vinegar is mixed with salt, the acetic acid in the vinegar reacts with the sodium chloride or salt to produce sodium acetate and hydrochloric acid. The hydrochloric acid is a strong acid.
What is a simple scientific experiment?
Simple Experiments in Scientific Research. A simple experiment is one researchers often use to determine if changes in one variable might lead to changes in another variable—in other words, to establish cause-and-effect.
What are the uses of baking soda and vinegar?
Use vinegar with baking soda to clean and deoderize. Using vinegar and baking soda together or separately as cleansing products not only cleans surfaces, but deodorizes too. Baking soda absorbs odors from refrigerators to drains to rugs and carpets, while offering a slightly abrasive tool to remove stubborn stains from cook tops or counters.
What is the chemical formula for vinegar and baking soda?
The chemical formula for baking soda is NaHCO3. The molecular mass of baking soda is 84.007 g/mol. Baking soda reacts with acids like vinegar to produce carbon dioxide gas. The chemical equation for the reaction with vinegar is CH3COO-Na+ + H2O + CO2.
