Hydrogen gas is given off when any acid reacts with metals. Acids must have at least 1 hydrogen in order to be recognized as an acid, so the metal takes the place of a hydrogen when it reacts and the metal becomes an ionic compound with whatever the hydrogen was bonded to in the acid and the hydrogen is on its own and is H2 gas.

∙ 8y agoNo. Burning metal consumes oxygen. Some metals can burn using some oxygen-containing substances instead of free oxygen, such as carbon dioxide or even water.

What are chemicals that eat away metal?
Acids, oxygen, water, certain molds, and rust.
What happens if acid is mixed with metal?
Generally, there occurs a chemical reaction with a wearing away of the metal. A salt and Hydrogen gas are produced. The following is the general formula for this reaction: ACID + (Active) METAL --> SALT + HYDROGEN. If the metal is not active such as Gold, then this reaction does not occur.
Why are acids not stored in metal containers?
Many acids react with most metals, often producing soluble substances. Acid + metal --> salt + water. This 'eats' away at the container and causes it to leak. Glass (almost always) and polythene are unaffected by acids. However, before the advent of polythene, concentrated sulfuric acid was stored in lead vessels.
An acid is a molecule that donates what?
Acid donates a hydrogen ion, a proton, to a solution. H +
How does the iron react when mixed with hydrochloric acid?
Acids produce hydrogen ions, H+. These ions take electrons away from iron atoms, turning them into ions, Fe++. The hydrogen is converted by this process back into its neutral atomic form, and bubbles away in the form of hydrogen gas, H2. The ionic iron remains dissolved in the aqueous solution, as part of the ferrous chloride compound.
Why are acids consider corrosive?
Because they can wear away metals and that produces hydrogen gas
What are chemicals that eat away metal?
Acids, oxygen, water, certain molds, and rust.
Why does potassium displace hydrogen ions from both acids and water?
Potassium is more reactive than hydrogen, which allows it to displace hydrogen from acids like many other metals. Unlike most metals it is reactive enough to pry away the more strongly-bonded hydrogen in water.
How do hydrogen ions give acidic character to acids?
Acids are proton donors. Since protons are H+ ions, an acid must have a proton to give away.

Why mineral acid is stronger than organic acid?
Not all mineral acids are stronger than all organic acids. An acid is a substance which releases hydrogen ions (H+) in water. The greater the degree of ionization, the stronger the acid. Strong acids ionize completely. One factor in the strength of an acid is the electronegativity of the atoms in it. Electronegative atoms tend to pull electrons away from the acidic hydrogen, making it easier for the ion to break away. The carbon and hydrogen of organic acids have relatively low electronegativities and so have a weak electron pull. By contrast many of the mineral acids contain multiple oxygen atoms or other electronegative elements such as nitrogen and the halogens.
What is the substance that accepts or binds hydrogen ions in a solution?
Buffers. They donate or take away H+ ions to or from a solution if it is needed to maintain constant pH.

Will an Acid produce same gas in all chemical reactions?
No, the word "acid" is far too vague,some acvids are solids some are liquids some are gasses. You need to define this better... EDIT: Acids can only be in aqueous solutions, so HCl dissolved in water is an acid, but when the water is taken away, HCl becomes nothing but a gas, that is NOT an acid. It is true that all acids contain hydrogen atoms (without which nothing is considered an acid!), and when acids react with metal, they make a salt and hydrogen gas. For example: 2HCl(aq) + 2Na -------> 2NaCl + H2 2HNO3 + Ca ---------> Ca(NO3)2 + H2 But when it reacts with something other than metals, Hydrogen gas might not be a product.

Does hydrogen give up valence electrons eaisly?
Yes, it can stabilize by giving away its electron, the reactions between an acid and a metal can be explained by this behavior.
