Which metal react with dilute hcl?
Many metals including alkali metals, alkali earth metals, chromium, nickel and zinc react with dilute hydrochloric acid.
Why hydrogen is liberated when magnesium react with dilute nitric acid unlike other metals where hydrogen is not evolved?
This may due to Magnesium metal has high reactivity and concentration of nitric acid is dilute, thus magnesium reacts with H+ in water/ in nitric acid to give hydrogen
Which metals react with dilute hydrochloric acid?
Potassium reacts explosively.
Why do some metals not react with acid?
Metals whose surfaces are "passivated" by for example the formation of an insoluble oxide do not react with acid. An example is aluminium which is resistant to dilute acid.
Do all metals react with acid then disappear?
No. First of all, the metal does not dissapear. When a a metal reacts with an acid it forms a corresponding salt, which usually then dissolves. Second, whther or not a reaction occurs depends on both the acid and the metal. Most metals will not react with a dilute weak acid. Some metals will not even react with most strong metals. Gold, platinum, and some platinum group metals will not react with acid except for aqua regia, a special mixture of hydrochloric and nitric acid. Ruthenium will not react with acid at all.
What two metals will react with dilute hydrochloric acid?
Two metals that will react with dilute hydrochloric acid are zinc and magnesium.

What is the gas made when metals react with dilute acid?
Hydrogen

Which metals do not react with dilute acid to produce hydrogen?
For example metals as Pt, Au, Os and other.
What happens when matals react with acid?
when metals react with acid hydrogen gas is liberated . and salt is formed eg; 2Na+2Hcl ------ 2Nacl+H2

What Gas produced when metals react with dilute hydrochloric acid?
Hydrogen gas. This can be tested via the 'pop' test.
What could happen if gold is placed in dilute hydrochloric acid?
Nothing, gold does not react with hydrochloric acid, if there are impurities of other metals in gold then impurities may react and form chloride salts.
Why hydrogen gas is not liberated when metals react with nitric acid?
Because Nitric acid is an unstable molecule and a very strong oxidizing agent (as compare to its acidic nature) so it oxidizes the liberated hydrogen into water molecules.
