all those metals which are present below Hydrogen in the reactivity series like Ag , Cu , Au , Pt ,etc.
^^ He is incorrect.
All metals, one or another, will react with some acids to produce Hydrogen Gas.
-He mentioned Copper and Silver. Silver and Copper will react with Nitric Acid giving off Hydrogen and NitroDioxide Gas.
He mentioned Gold and Platinum. Gold and Platinum will react with Aqua Regia (A mixture of Hydrogen Chloride and Nitric Acid) giving off Nitric Oxide, Nitrogen Dioxide, and Hydrogen gas.
All metals will react with FluoroAntimonic Acid, Xenic Acid, or any other super acid to give off hydrogen gas and other gases as well.

∙ 10y agoGenerally precious and semiprecious metals will not react with dilute acid. These include copper, gold, silver, platinum, and platinum group metals.
Gold and platinum will not even react with concentrated strong acids.

Which 2 metals can displace hydrogen from dilute nitric acid?
magnesium and manganese Mg(s) + 2 HNO3(aq) → Mg(NO3)2(aq) + H2(g)
The gas evolved when metals react with dilute acids?
When dilute acids and metals are mixed you will get Hydrogen gas and salts
What is the chemical equation for hydrochloric acid plus copper oxide?
No reaction will be observed. Copper is too unreactive and cannot displace hydrogen from hydrochloric acid. Only reactive metals (above hydrogen in the reactivity series) will react with dilute acids.
Which metal will displace hydrogen from an acid?
zinc magnesium aluminum iron nickel tin lead
What Gas produced when metals react with dilute hydrochloric acid?
Hydrogen gas. This can be tested via the 'pop' test.
Which 2 metals can displace hydrogen from dilute nitric acid?
magnesium and manganese Mg(s) + 2 HNO3(aq) → Mg(NO3)2(aq) + H2(g)
The gas evolved when metals react with dilute acids?
When dilute acids and metals are mixed you will get Hydrogen gas and salts
Do non metals liberate hydrogen gas from dilute. acids?
No. Metals liberate hydrogen gas from acids.
What is the gas made when metals react with dilute acid?
Hydrogen
Why hydrogen placed in activity chart of metals when it is not a metal?
Hydrogen may not be a metal, but it does share some properties with metals. It forms a positive cation, H+, and can displace some metals in displacement reactions. Basically, it is included in the reactivity series because it is able to displace some metals but not others.
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.
What is the chemical equation for hydrochloric acid plus copper oxide?
No reaction will be observed. Copper is too unreactive and cannot displace hydrogen from hydrochloric acid. Only reactive metals (above hydrogen in the reactivity series) will react with dilute acids.
Why most of the transition metal not displace hydrogen in acid?
because some metals are less reactive than hydrogen.
What is metallic behavior?
A metallic property is a type of chemical property that applies to metals. A couple of these properties include being able to displace a dilute acid's hydrogen and being able to be reduced.
Which metals do not react with dilute acid to produce hydrogen?
For example metals as Pt, Au, Os and other.
What two metals will react with dilute hydrochloric acid?
Two metals that will react with dilute hydrochloric acid are zinc and magnesium.
Which metal will displace hydrogen from an acid?
zinc magnesium aluminum iron nickel tin lead
