Why does metal react with vinegar?
Vinegar. Vinegar speeds up rusting because it contains a dilute form of acetic acid; positive hydrogen ions in the acid remove electrons from iron, ionizing it and making it susceptible to rust.
How does vinegar rust steel wool?
Steel Wool has a protective coating that keeps oxygen from coming into contact with the iron. Vinegar contains acetic acid which removes this coating. When the protective coating is removed, oxygen in the atmosphere can reach the iron in the steel wool and a chemical reaction called oxidation occurs. Rust is created.
Does steel wool rust faster in water or vinegar?
The vinegar damped steel wool probably rusted fastest because the acid of the vinegar removed the protective coating of the steel wool. Contrary to what was expected, the salt water dampened steel wool rusted more slowly than the plain water steel wool.
How long does it take for steel wool to rust in vinegar?
Let it Sit/React Let the vinegar dissolve the steel wool for at least two to three days. With the vinegar solution you definitely want to leave the lid off, as it releases a gas that you'll want to let escape from the jar.

What is the reaction between vinegar and sodium bicarbonate?
This reaction occurs in two steps. In the first, the acetic acid in vinegar reacts with sodium bicarbonate to produce sodium acetate and carbonic acid: Carbonic acid is unstable, and it quickly decomposes to form carbon dioxide and water: You can summarize the entire process with this equation:
How does vinegar react with baking soda?
Combine vinegar with baking soda ( sodium bicarbonate) and measure the temperature, and you'll find that it drops about 4 degrees Celsius (7.2 degrees Fahrenheit) in about a minute. Although the temperature drop isn't exactly a result of the specific reaction between vinegar and baking soda, it wouldn't occur if you didn't combine them, so the overall process qualifies as an endothermic reaction. The combination also releases carbon dioxide gas, which bubbles up inside the mixture to create a foam that rises out of the container like lava from a volcano.
How to clean rusty steel wool?
Place a fine steel wool pad in a glass container and pour in enough vinegar to cover it. Allow the pad to soak for about a minute, then remove it and place it in another container. Insert the end of a thermometer into the center of the pad and watch it for about 5 minutes. You'll see the temperature reading rise, and you may even notice fogginess on the side of the container if you use clear glass. Eventually the temperature will stop rising as the steel fibers get coated with a layer of rust, which blocks further oxidation.

How to determine if a reaction is exothermic or endothermic?
In addition to measuring the temperature change in a reaction, you can calculate the enthalpy change of a reaction. Enthalpy change is the sum of the energy used in bond breaking in reactants with the energy released in bond making in products. If the enthalpy change is negative, the reaction is exothermic because more energy is released in the products than was used to break up the reactants. A positive enthalpy change represents an endothermic reaction.
How does endothermic reaction work?
Endothermic reactions absorb heat, meaning the reaction uses more heat than is released in its products. Chemical reactions require energy to break bonds, but energy is released when new bonds form. In endothermic reactions, as bonds break, the reaction absorbs more energy than is released. You can observe this process by measuring ...
How to get a temperature of steel wool?
