The reaction is slow at room Metals below hydrogen Reaction of metal oxides with water: Most of the metal oxides are insoluble in water. Gold, platinum, ruthenium, tantalum, iridium, osmium, titanium, rhodium do not react with dilute nitric acid. It is, therefore, kept immersed in kerosene. However, aluminium has a protective oxide layer, so it reacts slowly with acids to begin with. Non metals have tendency to gain electrons, whereas metals have tendency to lose electrons easily. sulfuric acid and dilute hydrochloric sulfuric No, Copper does not react with non-oxidizing acid like dilute sulphuric acid, hydrochloride, hydrobromide, etc because its reduction potential is higher than that of hydrogen. Magnesium is the fastest and lead is Less reactive metal(Cu,Au,Ag) do not displace hydrogen from dilute acid.
