Metals will release hydrogen gas when reacting with an acid (or in some cases, water). This is because acids contain hydrogen, and many metals are higher on the reactivity series than hydrogen, meaning they will replace it in a compound. For example, zinc reacts with hydrochloric acid
Zn + 2HCl --> ZnCl2 + H2
The zinc replaces hydrogen in the hydrochloric acid, forming zinc chloride and releasing elemental hydrogen in the process.
What else can I help you with?
Acids generally release h2 gas when they react with what?
Acids generally release hydrogen gas when they react with metals, such as zinc or magnesium. This is due to the displacement of hydrogen ions from the acid by the metal, leading to the formation of hydrogen gas.
Do all metals react with acids to release hydrogen gas?
No: Only those metals that are higher in the electromotive series than hydrogen react with acids to release hydrogen gas. Examples of metals that never undergo this reaction are copper, silver, and gold. Also, even some metals that are higher than hydrogen in the electromotive series do not react rapidly enough to notice under ordinary conditions because of spontaneous formation of passive layers on their surfaces. Aluminum and austenitic stainless steels are examples of this group. These passivating metals will react, however, if their passive surfaces are broken by mechanical means.
The gas evolved when metals react with dilute acids?
When metals react with dilute acids, hydrogen gas is evolved. This is because metals displace hydrogen from the acid, resulting in the formation of metal salts and hydrogen gas as a byproduct. The reaction can be represented as metal + acid → metal salt + hydrogen gas.
What do metals react with acids to produce?
Metals react with acids to produce a salt and hydrogen gas.
When metals react with acid it form?
When metals react with acid, they typically form a salt of the metal and hydrogen gas. The metal displaces the hydrogen from the acid, resulting in the formation of a metal salt and the release of hydrogen gas as a byproduct.

Do non metals liberate hydrogen gas from dilute. acids?
No. Metals liberate hydrogen gas from acids.
What is the effect of acids on metals?
The acid may react which the metal to form a salt and release hydrogen gas.
The gas evolved when metals react with dilute acids?
When metals react with dilute acids, hydrogen gas is evolved. This is because metals displace hydrogen from the acid, resulting in the formation of metal salts and hydrogen gas as a byproduct. The reaction can be represented as metal + acid → metal salt + hydrogen gas.
What do metals react with acids to produce?
Metals react with acids to produce a salt and hydrogen gas.
What gas is produced when metals react with an acid?
Hydrogen
When metals react with acid it form?
When metals react with acid, they typically form a salt of the metal and hydrogen gas. The metal displaces the hydrogen from the acid, resulting in the formation of a metal salt and the release of hydrogen gas as a byproduct.
What gas is produced when metals are put in hydrochloric acid?
When metals are put in hydrochloric acid, hydrogen gas is produced as the metal reacts with the acid to form metal chloride and hydrogen gas as a byproduct.
Do acids and metals react to make oxygen?
Acids can react with metals to produce hydrogen gas, not oxygen. When acids react with metals, they displace hydrogen gas from the acid.
When acids react with active metals they always produce what?
When acids react with active metals, they always produce a salt and hydrogen gas.
What is the gas produced when metals react with acids?
Hydrogen gas is produced when metals react with acids. This reaction typically involves the metal displacing hydrogen from the acid to form metal salts and hydrogen gas.
