What is the net ionic equation for copper and nitric acid?

Answer 1

This reaction occurs in two steps.

1) Copper is oxidized by concentrated nitric acid.

3Cu + 2HNO3 = 3CuO + 2NO + H2O

2)The copper oxide is attacked by the excess HNO3:

3CuO + 6HNO3 = 3Cu(NO3)2 + 3H2O

I put 3 CuO because there are 3 parts of CuO resulting from the first reaction and so, there are 3 parts of CuO reacting with the excess acid.

Replacing the CuO with 3Cu(NO3)2 + 3H2O in the first equation, we have:

3Cu + 8HNO3 = 3Cu(NO3)2 + 2NO + 4H2O

I put 8 parts of nitric acid because there are two parts that form the oxide and six parts that form the copper nitrate.

There is also a second reaction, where NO reacts with oxygen in the air to form NO2, a very, very, very poisonous reddish-brown gas, but that's not part of the copper + nitric acid reaction

Answer 2

The net ionic equation for the reaction between copper and nitric acid is Cu(s) + 2H⁺(aq) + 2NO₃ˉ(aq) → Cu²⁺(aq) + 2NO₃ˉ(aq) + H₂(g). In this reaction, copper is oxidized to form copper(II) ions, and nitric acid is reduced to form water and nitrogen dioxide gas.

Answer 3

Cu + 4HNO3 ---> Cu(NO3)2 + 2NO2(g) + 2H2O

Answer 4

what is the net ionic epqation for copper nitrate

Answer 5

Copper Carbonate + Nitric Acid --> Copper Nitrate + Carbon Dioxide

Answer 6

[Cu(H2O)6]^2+ + 2OH^- -> [Cu(H2O]4(OH)2] + 2H2O . Copper hydroxide formed is a pale blue precipitate.

Answer 7

The reaction is:
CuO + 2 HNO3 = Cu(NO3)2 + H2O

Answer 8

This equation is:
Cu2+ + 2 OH- = Cu(OH)2 (s)

Answer 9

1 CuO + 2 HNO3 --> 1 Cu(NO3)2 + 1 H2O

Answer 10

copper nitrade + water :)
