It depends which metal you are referring to.
Hydrogen gas is produced when an acid reacts with a metal. This is because the acid reacts with the metal to form a salt and hydrogen gas.
A salt. The type of salt depends on the type of acid.
When metal reacts with acid, hydrogen gas is produced. This is due to the displacement reaction where the metal displaces hydrogen from the acid to form hydrogen gas and a metal salt.
hydrogen gas
Hydrogen gas is produced when any metal reacts with acids. This is a common reaction that is often used to test for the presence of metal in a substance.
Hydrogen gas is often produced when a metal reacts with an acid. This reaction is a common way to test for the presence of a metal in a compound.
Hydrogen gas is produced when a metal reacts with a dilute acid. This reaction occurs when the metal displaces hydrogen from the acid, forming metal salts and releasing hydrogen gas as a byproduct.
Oxygen
What is produced when a acid reacts with a metal
The gas produced is hydrogen gas (H2). The reaction between sodium metal and water is a highly exothermic reaction that liberates hydrogen gas, which in turn reacts explosively with oxygen in the air when ignited by a burning splint.
When a metal reacts with an acid, hydrogen gas is usually produced along with an aqueous metal salt. The metal displaces hydrogen from the acid to form the metal salt, while hydrogen gas is released as a byproduct of the reaction.
The gas that is typically produced when a metal reacts with an acid is hydrogen. However, other gases could be released depending on which metal and acid is used.
