A protective layer is formed at the surface of aluminium; the phenomenon is called passivation.
Add to several drops of sulfuric acid a few grains of barium chloride; a white precipitate of barium sulfate is obtained.
Sulfuric acid (H2SO4) is more acidic than nitric acid (HNO3).
Nitric acid can be dilute or concentrated. This is simply a matter of how much of it you have in a given amount of a solution, which is variable.
You can use either the nitric or hydrochloric acid as a replacement of the sulphuric acid.
Fertilisers contain Sulphuric acid.
Mercury is not attacked by dilute hydrochloric or sulfuric acid. It reacts with hot nitric acid to form mercuric nitrate, Hg(No 3 )
hydrochloric
Cu + 2HNO3 -> Cu(NO3)2 + H2 Ideally, yes. How dilute? In school experiments the nitric acid would be dilute.
Nitric Acid is used to make Ammonium Nitrate
Nitric acid is an electrolyte.
