For example metals as Pt, Au, Os and other.
Most metals react with dilute acids to form metal salts and hydrogen gas. For example, metals like magnesium, zinc, and iron will react with acids such as hydrochloric acid or sulfuric acid to produce hydrogen gas.
Hydrogen
Metals like magnesium, zinc, iron, and aluminum react with dilute hydrochloric acid to produce hydrogen gas and a metal chloride salt. These reactions are examples of single displacement reactions, where the more reactive metal displaces the hydrogen from the acid.
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.
Reactive metals like magnesium, zinc, and aluminum will react the most vigorously with dilute acid. The reaction will produce bubbles of hydrogen gas and a salt.
Lots of metals will react with dilute hydrochloric acid; anything above hydrogen in the activity series should do so.
When metals react with dilute acid, hydrogen gas is liberated. This is because the reaction between the metal and the acid displaces hydrogen from the acid, resulting in the formation of hydrogen gas bubbles.
Metals react with acids to produce a salt and hydrogen gas.
Metals such as magnesium, zinc, iron, and aluminum can react with dilute hydrochloric acid to produce hydrogen gas and metal chloride salts. Copper, silver, and gold do not react with hydrochloric acid under normal conditions.
All the metals above Hydrogen in electro chemical series as K,Na,Ca,Mg,Fe e.t.c when react with dilute acids produce hydrogen gas.
When dilute acids react with metals, hydrogen gas is typically produced. This is due to the displacement of hydrogen ions in the acid by the metal atoms, resulting in the formation of hydrogen gas bubbles.
When acids react with active metals, they always produce a salt and hydrogen gas.
