Why does copper not react with most acids but does react with nitric acid?
Nitric acid reacts with copper because of the nitrate ion. It is the nitrate ion that causes the copper to dissolve, not the H. There is no reaction between copper and HCl because neither H nor Cl is able to react with the metal.
Why does copper have a low reactivity?
The poor shielding by the d orbital electrons makes the atoms of Cu much smaller in size. The d electrons in Cu are involved in metal bonding and so it has higher Melting and boiling points. Copper has higher hydration enthalpy and higher ionization energy hence it tends to be unreactive.
What happens when you mix copper and nitric acid?
Concentrated nitric acid reacts with copper and produce copper nitrate ( Cu(NO3)2 ), nitrogen dioxide (NO2) gas and water as products. In this reaction, copper is oxidized to its +2 oxidation state while nitric acid is reduced to nitrogen dioxide.
Is copper reactive than hydrogen?
Copper is less reactive than hydrogen as it is below hydrogen from reactivity series.
Why does copper not react with sulfuric acid?
Copper does not react with dilute sulphuric acid. This is because copper is lower in reactivity series than hydrogen. Copper has higher reduction potential than that of hydrogen. Thus, copper cannot displace hydrogen from the non-oxidising acid.
Is copper the least reactive metal?
Which is the least reactive metal in the reactivity series? A-Copper. As we can see in the series, out of all the given options gold is the least reactive metal. So, option D is correct.
Why does copper not react with any other gases in the air?
This excess oxygen is present in the copper matrix as a copper oxide. IF this grade of copper is heated over 425C. in an atmosphere with some hydrogen (more than 4 or 5 \% will do it) at a temperature, the hydrogen diffuses rapidly through the copper ( hydrogen loves to do this with copper).
